Brian Protheroe (born 16 June 1944, Salisbury, Wiltshire), born of a Welsh father and English mother, is a musician and actor.

Protheroe joined a local church choir when he was twelve years old, and started piano lessons at about the same time. The music of Cliff Richard and The Shadows inspired him to start learning the guitar. He joined a rock band called The Coasters (not to be confused with the similarly titled United States outfit) as lead singer in 1961, and also joined an amateur theatre group called The Studio Theatre.

Protheroe's first job was a library assistant for a year followed by three years as a student technician in a hospital pathology laboratory. Musical influences around this time were Elvis Presley, The Everly Brothers, Josh White, Big Bill Broonzy, Sonny Terry and Brownie McGhee, Dave Brubeck, and the choral church music of Bach.

Protheroe joined the folk group, Folk Blues Incorporated (FBI) when he was nineteen, while at this time listening to Bob Dylan and The Beatles. He came to London with FBI in 1965, and played in folk music clubs in and around London. In 1966, Protheroe began his career as an actor. His first job was with his local repertory theatre in Salisbury. He worked there for about seven months then spent the next five years in various theatre companies around England, developing his musical skills as well as becoming an experienced actor. In 1968 he worked for nearly two years in a theatre company in Lincoln, where he met Martin Duncan who was also a musician, writer and actor. Over the next few years they collaborated on various musical and artistic projects.

Ian Scott Anderson, MBE (born 10 August 1947) is a Scottish singer, songwriter and multi-instrumentalist, best known for his work as the leader and flautist of British rock band Jethro Tull.

Ian Anderson was born the youngest of three children. His father, James Anderson, ran the RSA Boiler Fluid Company in East Port, Dunfermline, Fife, Scotland. Anderson spent the first part of his childhood in Edinburgh, Scotland. He was influenced by his father's big band and jazz records and the emergence of rock music, though disenchanted with the "show biz" style of early American rock and roll stars like Elvis Presley.

His family moved to Blackpool, Lancashire in 1959, where he gained a traditional education at Blackpool Grammar School. In a recent interview, Anderson stated that he was asked to leave Grammar School for refusing to submit to corporal punishment (still permitted at that time) for some serious infraction. He went on to study fine art at Blackpool College of Art from 1964 to 1966.

While a teenager, Anderson took a job as a sales assistant at Lewis' department store in Blackpool, then as a vendor on a newsstand. He later said it was reading copies of Melody Maker and the New Musical Express during his lunch breaks that gave him the inspiration to play in a band.

Barrie "Barriemore" Barlow (born 10 September 1949, Birmingham) is an English musician, best known as the drummer and percussionist for the rock band Jethro Tull, from May 1971 to June 1980.

Christened Barrie, the 'Barriemore' was an affectation to suit the eccentric image of Jethro Tull (much as Jeffrey Hammond had become "Jeffrey Hammond-Hammond").

Barlow was a school friend, and former bandmate of Jethro Tull frontman Ian Anderson. He joined after the departure of Clive Bunker and played on the following albums:

Upset by the death of bassist John Glascock, Barlow left Jethro Tull in 1980, after completing the final leg of the Stormwatch tour.

Barlow went on to do various session projects, including work with Robert Plant, John Miles, and Jimmy Page, and he also started his own band for a spell called Storm. He played on the Yngwie Malmsteen album Rising Force. He played on the Kerry Livgren album, Seeds of Change.

Barlow has a recording studio, The Doghouse, on his property in Shiplake, Oxfordshire, England. He is currently managing a band from Henley on Thames called The Repertoires, and has also been linked with other local bands which echo his own folk-influenced musical history, such as Reading's Smokey Bastard.
