I had a similar experience, and the wonderful McIntosh Reverse Stereo saved the day.
We saw Hot Sardines live, amazing
big stage, main line: tuba far left, horns progressing l to r, bass, drums center slightly behind the horn line, piano far right
front, tap dancer slightly off center left, singer slightly off center right
Then I bought this double album (also terrific, live from Joe's Pub, NYC and Live from Toronto, Canada). I highly recommend this LP.
Piano left, horns right, everything reversed.
Turned out, Donna had been to the show at Joe's Pub, and the narrower stage was a jumble of players. indeed piano left.
After knowing that, and getting used to the LP's, I am able to listen as recorded.
You can tell the difference between sites (they are mixed up) by the imaging width, Toronto a wider stage, and deeper hall.
