Can't think of any recordings, but I remember going to a Judy Collins concert in the late 70s. Gorgeous voice, of course, but (much to my surprise) frequently off-pitch enough to cause me to wince. Don't know if she was having an off day or what, but I found it hard to believe how bad her pitch was -- and repeatedly.

An aside:
Dave in Michigan, Hi again! Your "clues" in the other thread helped some, but not enough (clearly your memory is better than mine). There are at least a couple of Daves I think you might be, but I am far from sure. (The number of Daves I know is almost amazing. I remember once receiving a holiday card signed simply "Dave". To this day, I don't know who sent it...)

How about e-mailing me at: vikkivikki@@srama..srama..demon..demon..co..co..uk..uk
(@ddress doubled to avoid spambots; I'm sure you can figure out what it should be)

Apologies for hijacking the thread, but I can't PM Dave, as he's not a member.
