My parents go and see this covers band called Cry Wolf in pubs near where they live. I've seen them a few times myself too.

They're a bunch of all guys playing covers mostly from the 70s/80s, and the odd contemporary song that old people think is 'rock music' like Nickelback or something. They have a suitably shit website too: http://www.crywolfrocks.co.uk/

Anyway, it turns out that three main guys (brothers as it turns out) were actually in a fairly successful glam-rock band in the 70s called Blackfoot Sue. Despite being aware of Cry Wolf for years, I wasn't aware of their history as a 'proper' band with a couple of LPs and a string of singles - and it turns out that they are/were pretty incredible!

Here they are playing their biggest hit, 'standing in the Road' on what seems to be some German version of Top of the Pops: http://www.youtube.com/watch?v=7e6FDlS12qo

Here they are playing their follow-up single on a different TV show. The breakdown, solo, and fade-in from one minute on is incredible: http://www.youtube.com/watch?v=SbzpD_Ap9bs

Here's a kind Black Sabbath/Led Zep stomper with suitably psych lyrics called 'Messiah' from their debut album: http://www.youtube.com/watch?v=3lFSH_HkAQM

Basically, never underestimate the old rockers at the local pub - you never know who they might be!
