Wham! were a British musical duo formed by George Michael and Andrew Ridgeley in the early 1980s. They were briefly known in the United States as Wham! UK due to a naming conflict with an American band.

Wham! sold 25 million certified records worldwide from 1982 to 1986.

Michael and Ridgeley met at Bushey Meads Comprehensive School in Bushey near the suburb of Watford in Hertfordshire, England, UK. At first they performed in a short-lived ska band called The Executive, alongside three of their former school friends David (Austin) Mortimer, Harry Tadayon and Andrew Leaver. When this group split, Michael and Ridgeley eventually formed Wham!, signing with Innervision Records, a contract they later sued to be released from. Once that situation was resolved, they signed with CBS (Columbia Records in the United States and Canada, and Epic Records for the rest of the world).

Michael took on the majority of roles and responsibilities within the band—composer, producer, singer, and occasional instrumentalist. Ridgeley convinceda reluctant Michael that Wham! needed to change their image and their sound frequently, from the leather-clad moody singers of "Bad Boys" and "Young Guns (Go for It!)" to the more fashionable pop superstars of "Wake Me Up Before You Go-Go".

David Howell Evans (born 8 August 1961), more widely known by his stage name The Edge (or just Edge), is a musician best known as the guitarist, backing vocalist, and keyboardist of the Irish rock band U2. A member of the group since its inception, he has recorded 12 studio albums with the band and has released one solo record. As a guitarist, The Edge has crafted a minimalistic and textural style of playing. His use of a rhythmic delay effect yields a distinctive ambient, chiming sound that has become a signature of U2's music.

The Edge was born in England to a Welsh family, but was raised in Ireland after moving there as an infant. In 1976, at Mount Temple Comprehensive School, he formed U2 with his fellow students and his older brother Dik. Inspired by the ethos of punk rock and its basic arrangements, the group began to write its own material. They eventually became one of the most popular acts in popular music, with successful albums such as 1987's The Joshua Tree and 1991's Achtung Baby. Over the years, The Edge has experimented with various guitar effects and introduced influences from several genres of music into his own style, including American roots music, industrial music, and alternative rock. With U2, The Edge has also played keyboards, co-produced their 1993 record Zooropa, and occasionally contributed lyrics. The Edge met his second and current wife, Morleigh Steinberg, through her collaborations with the band.

George Michael (born Georgios Kyriacos Panayiotou (Greek: Γεώργιος Κυριάκος Παναγιώτου); 25 June 1963) is an English musician, singer, songwriter, multi-instrumentalist and record producer. Michael rose to fame in the 1980s when he formed the pop duo Wham! with his school friend, Andrew Ridgeley. His first solo single, "Careless Whisper", was released when he was still in the duo and sold about six million copies worldwide.

As one of the world's best-selling music artists, Michael has sold more than 100 million records worldwide as of 2010. His 1987 debut solo album, Faith, has sold more than 20 million copies worldwide and made several records and achievements in the United States. Michael has garnered seven number one singles in the UK and eight number one hits on the Billboard Hot 100 in the US. In 2008, Billboard magazine ranked Michael the 40th most successful artist on the Billboard Hot 100 Top All-Time Artists list.

Michael has won numerous music awards throughout his 30-year career, including three Brit Awards—winning Best British Male twice, four MTV Video Music Awards, four Ivor Novello Awards, three American Music Awards, and two Grammy Awards from eight nominations.
