Did You Know...

Def Leppard formed in 1977 as a high school cover band. The original name was properly spelled, and the original lineup included singer Joe Elliot, bassist Rick "Sav" Savage, guitarist Pete Willis, and drummer Tony Kenning. At this time, the band's only gig was playing David Bowie and Thin Lizzy covers for friends.

In 1978, they picked up second guitarist, Steve Clark, and practiced relentlessly. Tony Kenning was fired and replaced by Frank Noon for their first recording, The Def Leppard EP. Frank Noon was then replaced by Rick Allen. In 1979, the band's reputation grew as they received their first airplay on BBC 1. Leppard then signed major contracts with Phonogram and Mercury, and quit their day jobs.

They immediately scored quality gigs, opening for both Sammy Hagar, and AC/DC during a two months' span. Leppard's first single, "Wasted," produced by Rick Tauber, was released, and their popularity began to grow. In 1980, Def Leppard produced their debut LP, On Through the Night. This was also the year of their arrival in America, touring with Pat Travers, Judas Priest, Ted Nugent, and AC/DC. The tour was successful, but gave rise to hostility back in the UK.
