Jeffrey "Jeff" Lynne (born 30 December 1947) is an English songwriter, composer, arranger, singer, multi-instrumentalist, and record producer who gained fame as the leader and sole constant member of Electric Light Orchestra. He was later a co-founder and member of The Traveling Wilburys together with George Harrison, Bob Dylan, Roy Orbison, and Tom Petty. Lynne has produced recordings for artists such as The Beatles, Brian Wilson, Roy Orbison, Dave Edmunds, Del Shannon and Tom Petty. He has co-written songs with Petty and also with George Harrison, whose 1987 album Cloud Nine was co-produced by Lynne and Harrison. Among the many compositions to his credit are such well-known hits as "Livin' Thing", "Evil Woman", "Turn to Stone", "Do Ya", "Xanadu", "Strange Magic", "Sweet Talkin' Woman", "Telephone Line", "Shine a Little Love", "Mr. Blue Sky", "Hold On Tight", "All Over the World", and "Don't Bring Me Down".

In 2008, The Washington Times named Lynne the fourth greatest record producer in music history.

Gareth Malone (born Bournemouth, 1975) is a British choirmaster and broadcaster, self-described as an "animateur, presenter and populariser of choral singing". He is best known for his television appearances in programmes such as The Choir which focus on singing and introducing choral music to new participants.

Gareth Edmund Malone was educated at Bournemouth School, and sang with the Symphony Chorus of the Bournemouth Symphony Orchestra (BSO). He studied drama at the University of East Anglia, Norwich where he was in the university choir and composed music for theatre productions. After graduating he did private tuition and then applied for a postgraduate vocal studies course at The Royal Academy of Music. He passed with distinction in 2005.

Working at the LSO he was awarded the position of Edward Heath Assistant Animateur in 2001. He entered television work when approached by 20/20, a production company which wanted to make a series about singing in schools. Without knowing who could front the programme they had researched the term "community choirmasters" and discovered Malone’s name. The Choir was very successful, winning two BAFTAs and a Broadcast award.

Richard Tandy (born 26 March 1948, in Birmingham, England), is best known as the keyboard player in the rock band, Electric Light Orchestra ("ELO"). His palette of keyboards (including Mini Moog, clavinet, mellotron, and piano) was an important ingredient in the group's sound, notably on the albums A New World Record, Out of the Blue, Discovery, and Time.

A former pupil of Moseley School, where he first met future bandmate Bev Bevan, Tandy would later be reunited with Bevan in 1968 when he played the harpsichord on The Move's number one chart-topper "Blackberry Way". Later, in 1972, Tandy was the bass player in the first live line-up of ELO, then switching to keyboards when Jeff Lynne decided that their live sound needed improvement. Tandy was often seen on stage playing the stereotypical 1970s prog-rock stack of keyboards, with bass pedals under his feet. As well as ELO, he has collaborated musically with Jeff Lynne on many projects, among them songs for the Electric Dreams soundtrack, Lynne's solo album Armchair Theatre and Lynne produced Dave Edmunds "Information". Tandy's playing has been loosely compared to that of Tony Banks, by some with the patch engineering quality of Tomita. Before joining ELO Tandy played with the groups The Uglys and Balls.

Thomas Earl "Tom" Petty (born October 20, 1950) is an American singer-songwriter and multi-instrumentalist. He is the frontman of Tom Petty and the Heartbreakers and was a founding member of the late 1980s supergroup Traveling Wilburys and Mudcrutch. He has also performed under the pseudonyms of Charlie T. Wilbury, Jr. and Muddy Wilbury.

He has recorded a number of hit singles with the Heartbreakers and as a solo artist, many of which remain heavily played on adult contemporary and classic rock radio. His music, and notably his hits, have become popular among younger generations as he continues to host sold-out shows. Throughout his career, Petty and his collaborators have sold 60 million albums.

Tom Petty was born and raised in Gainesville, Florida, and attended Gainesville High School. His interest in rock and roll music began at age 10 when he met Elvis Presley. In the summer of 1961, his uncle was working on the set of Presley's film Follow That Dream in nearby Ocala, Florida and invited Petty to come down and watch the shoot. He instantly became an Elvis Presley fan and soon traded his Wham-O slingshot for a box of Elvis 45s. In a 2006 interview on the National Public Radio program Fresh Air, Petty said that he knew he wanted to be in a band the moment he saw The Beatles on The Ed Sullivan Show. One of his first guitar teachers was Don Felder, a fellow Gainesville resident, who would later join the Eagles. As a young man, Petty worked briefly on the grounds crew for the University of Florida, but never attended as a student. An Ogeechee lime tree that he planted while employed at the University is now called the Tom Petty tree.

Stephen Lawrence "Steve" Winwood (born 12 May 1948) is an English songwriter and musician whose genres include blue-eyed soul, R&B, rock, blues-rock, pop-rock, and jazz. A multi-instrumentalist, he plays the electric organ, synthesizers, bass, drums, guitar, mandolin, violin and other strings. A star performer for nearly 50 years, he has also done notable work as a producer.

In addition to his solo career, Winwood was a key member of The Spencer Davis Group, Traffic, Blind Faith and Go. He was inducted into the Rock and Roll Hall of Fame as a member of Traffic in 2004.

In 2005, Winwood was honoured as a BMI Icon at the annual BMI London Awards for his "enduring influence on generations of music makers." In 2008, Rolling Stone magazine ranked Winwood #33 in its 100 Greatest Singers of All Time. Winwood has won numerous Grammy Awards in the United States.

Stephen Lawrence Winwood was born in Handsworth, Birmingham, England. His father, Lawrence, a foundryman by trade, was a semi-professional musician, playing mainly the saxophone and clarinet. Young Winwood became interested in swing and Dixieland jazz as a boy and began playing drums, guitar, and piano. He first performed with his father and older brother Muff in the Ron Atkinson Band at the age of eight. Winwood was a choirboy at St John's Church Perry Barr and later admitted to having "sneaked a few plays" of the organ there. While he was still young the family moved from Handsworth to the semi-rural suburb of Kingstanding at the northern edge of the city.
