could be: The Coatham Bowl, 1973
Cotham Bowl Redcar
Paul Rodgers
Simon Kirke
John "Rabbit" Bundrick
Paul Kossoff
Tetsu Yamauchi
the sound quality is clear(SB) but the audio speed seems to run a little slow
and the show its self is pretty poor with kossoff obviously not too with it in
the later shows playin some chringeworthy stuff(notably Wishing Well)
Koss is in terrible shape as noted above. the band was told after this show that they would never be invited back to this venue. This was doubly devastating as this was a venue where Free had ruled the roost only a year or so earlier. This is the show where another member of the band calls Koss a "fucking little wanker" after he finishes "Wishing Well" in the wrong key. They eventually turn him off for the remainder of the show, and Rodgers plays guitar.
also, Rabbit's tune (On the Run) is terrible too. not a great live singer although a great keyboard player. Koss sounds as if he starts off the show almost coherent but whatever it was he took backstage beforehand (more than likely Mandrax) catches up with him fast and he is unable to make even a basic chord come from his guitar.
