Roots of On Through the Night

Thin Lizzy were an Irish rock band formed in Dublin in 1969. The band initially consisted of bass guitarist, lead vocalist, and principal songwriter Phil Lynott, drummer Brian Downey, guitarist Eric Bell, and organist Eric Wrixon, although Wrixon left after a few months. Bell left at the end of 1973 and was briefly replaced by Gary Moore, who himself was replaced in mid-1974 by dual lead guitarists: Scott Gorham, who remained with the band until their break-up in 1983, and Brian Robertson, who remained with the band until 1978 when Moore re-joined. Moore left a second time and was replaced by Snowy White in 1980, who was himself replaced by John Sykes in 1982. The line-up was augmented by keyboardist Darren Wharton in 1980.

UFO were an English rock band formed in London in 1968. They became a transitional group between early hard rock and heavy metal and the new wave of British heavy metal (NWOBHM). The band's final line-up consisted of vocalist Phil Mogg, lead guitarist Vinnie Moore, rhythm guitarist and keyboardist Neil Carter, bass guitarist Rob De Luca, and drummer Andy Parker. They had gone through several line-up changes, leaving Mogg as the only constant member, and had disbanded three times. The band's "classic" line-up comprised Mogg, Parker, bassist Pete Way, keyboardist Paul Raymond, and former Scorpions guitarist Michael Schenker. In May 2018, Mogg announced that he would retire from UFO after one last tour as a member of the band in 2019; however, their farewell tour was set to conclude in 2022 before it was cancelled, due to Mogg's health issues. Mogg confirmed UFO's third disbandment in April 2024.

Mott the Hoople were an English rock band formed in Hereford, Herefordshire in 1966. Originally named the Doc Thomas Group, the band changed their name after signing with Island Records in 1969. The band released albums at the beginning of the 1970s but failed to find any success. On the verge of breaking up, the band were encouraged by David Bowie to stay together. Bowie wrote their glam-style signature song "All the Young Dudes" for them, which became their first hit in 1972. Bowie subsequently produced their album of the same name, which added to their success.
