Larry's original thread was probably deleted for "business" purposes (let's just not provide a link & see how it goes from here on out)...and I don't remember if it's exactly a half step, but it's pretty darn close to it if it's not. You can never be exactly sure about club dates like this, given the conditions of pianos, players natural intonations, etc, but you can get a general pitch center for the tunes, and in this case, slowing it down about a half step will fix it.
20 or so years ago, having a variable speed turntable made fixing it a piece of cake. Not sure what the digital fix is, but it's probably even easier. And it needs to be done.
