Thank you to all who have responded. It has been enlightening and useful. I am aware of the Discogs site and probably will check it out again. .
I have a copy of "Tommy" and it sounds good, but in anticipation of buying a better table and cartridge, I thought I would post this thread. I am not sure how old my copy is. The cover is in good shape; but, side four is marred by pops and clicks, no matter how much I clean it
May have to consider the SACD version recommended by member
