To contrast the Rio gig, the above is from a taped show in 1974 at some middle school in Canada. (I’m not sure the crowd quite knew how to handle it!) Paul Rutsey on drums.
At 27:20 is the start of Working Man. Much longer guitar solo, almost sounds improvised in places, just jamming. Amazing sound too. I would put it as their best version.
Young pups back then, going after their dream. I’m glad they succeeded so the rest of us good enjoy it!
