It's a shame that they went all strange and crap after there Rocking all over the World shite cover, but I think Status Quo's 1st live album should get mentioned. The album was recorded in Glasgow's Apollo Theatre in 1976 and it rocks hard.
It's a real live recording, easy to spot, it contains a fair bit of mistakes but the intensity and crowd participation more than makes up for it.
Praising the Quo might not be a popular thing to do but this album is fucking ace !
