Yes, even the mighty Status Quo were young in 1972, when these pictures were taken by their tour manager, song writer and harmonica player, Bob Young. His website has lots of Quo goodies and can be found here.
I used to love Quo years ago, but l can't say l have been interested in any of their new stuff for years. They also have a movie coming out soon (Bula Quo), and l am dreading it, as the clips l have seen in advance of it don't exactly make me think it will be any good. Hopefully it will be so bad and tongue in cheek, it may actually be decent in an 'ironic' sense, but l very much doubt it. The trailer is here. Feast your eyes.
