I originally bought Billion Dollar Babies on tape when it came out... played it to absolute death and back... the last tracks on each side are reversed to those on the vinyl release... still throws me, even though I now have the "deluxe" cd, which now lives on the ipod... 36 years... wow, don't they just fly by...
I was loaned a copy of "Fumblin Towards Exctasy" (still one of my favourite recordings, and not ashamed to say so) which was eventually gifted, which I taped and loop-played, but I transposed the "bonus" track - Joni Mitchell's "Blue" to the beginning, and cut the air between the end and the hidden piano only version of "Possession"... sounds so wrong any other way...
There are numerous others...
I can not get over my embarrasment at calling "Little Wing" a Derek & the Dominoes song, when talking to the late SRV about the set I had just watched him play at Reading in '83 ("... Hendrix wrote that..." he corrected, said with a broad smile - what a loss), but it is that version I heard first, and it just sticks with me...
