I've just realized that Heartbreak city is on the Anthology album, but I prefer the version posted here, or maybe they're both the same version but the one posted has been cleaned up a lot, but there are no keyboards in the anthology version?
It's amazing how different both versions sound. Mind you, maybe not, the other day I searched out lots of different versions of Blue Moon on the youtube and recorded them to tape one after the other and listened to them all through and they all sounded like different songs. I also tried this with Dream a Little Dream. The Louis Armstrong version, the Mamas & Papas version. I was surprised to find that there was a Terry Hall version. There are more versions of Blue Moon than there are Dream a Dream. I wouldn't be surprised if there were more versions of blue moon than any other song considering how many were listed. Would have taken me all night if I'd played each one. In fact it did take me all night and I didn't get to play each one.
