 McCulloch was a member of the Glasgow psychedelic band One in a Million (formerly known as the Jaygars), Thunderclap Newman, and Stone the Crows.
 He also made appearances on many albums, including John Entwistle's "Whistle Rymes" in 1972, as lead guitarist playing alongside Peter Frampton on "Apron Strings" and "I Feel Better"; and on Roy Harper's album, "Bullinamingvase", and Ricci Martin's album, "Bleached", both in 1977.
 McCulloch also played guitar on Roger Daltrey's album "One of the Boys" which was released in 1977.
 McCulloch was a friend of the Who and a member of the band Thunderclap Newman, which was created and produced by his mentor Pete Townshend.
 At age 11, he was also a protégé of the Shadows' Hank Marvin.

The Waterboys are a Scottish/Irish folk rock band formed in Edinburgh in 1983 by Scottish musician Mike Scott.
 The band's membership, past and present, has been composed mainly of musicians from Scotland and Ireland with Edinburgh, Dublin, Spiddal, New York and Findhorn, serving as homes for the group.
 Mike Scott has remained as the only constant member throughout the band's career.
 They have explored a number of different styles, but their music is mainly a mix of Celtic folk music with rock and roll.
 They dissolved in 1993 when Scott departed to pursue a solo career.
 They reformed in 2000, and continue to release albums and tour worldwide.
 Scott emphasises a continuity between The Waterboys and his solo work, saying that "To me there's no difference between Mike Scott and the Waterboys; they both mean the same thing.
 They mean myself and whoever are my current travelling musical companions."

"Mull of Kintyre" is a song by the British-American rock band Wings written by Paul McCartney and Denny Laine.
 The song was written in tribute to the picturesque Kintyre peninsula in Scotland and its headland, the Mull of Kintyre, where McCartney has owned High Park Farm since 1966.
 The song was Wings' biggest hit in Britain where it became the 1977 Christmas number one, and was the first single to sell over two million copies nationwide.
Alexander Paul Kapranos Huntley (born 20 March 1972) is a Scottish musician, singer, songwriter, record producer, and author.

Wings Over the World is a 1979 television documentary film featuring the rock band Wings.
 It consists of concert performances from their acclaimed 1975–76 world tour, together with behind-the-scenes footage.
 Also included is a short excerpt of Wings rehearsing at London's Institute of Contemporary Arts before their 1972 UK university tour.
 Problems with the audio from the 1976 live performances delayed the film's release until March 16, 1979 in the United States (on CBS) and April 8, 1979 in the United Kingdom (on BBC2), by which time, band members Jimmy McCulloch and Joe English had left the group and been replaced.
The Wings Over the World tour was a series of concerts in 1975 and 1976 by the British–American rock band Wings performed in Britain, Australia, Europe, the United States and Canada.
 The North American leg constituted band leader Paul McCartney's first live performances there since the Beatles' final tour, in 1966, and the only time that Wings played in the US and Canada.
 The world tour was well-attended and critically acclaimed, and resulted in a triple live album, "Wings Over America", which Capitol Records released in December 1976.
 In addition, the tour was documented in the television film "Wings Over the World" (1979) and a cinema release, "Rockshow" (1980).
