Leppard was founded, like many bands in Sheffield at that
time, in 1977.
By 1979 their success enabled them to quit their day jobs
and focus on music. They outgrew Sheffield soon and become
initially more successful in the USA than the UK. Their
third album Pyromania finally gave them their big break
worldwide and in the UK.
They were more part of the rock music scene in Sheffield
and initially had more of a big following outside the
UK, so they weren't around in Sheffield
when the music scene in Sheffield peaked in 1980.
Even still, there is an early connection between Joe Elliot
and Stephen Singleton (Vice Versa/ABC), who were mates
at primary school where they formed their own band. They
went to different schools after that, so they went their
own ways, both ending up in very successful bands
in totally different genres of music.
