I think most of the brussels discs out there are actually a combo of the 10/17 show from Belgium and a London show, maybe 9/9/73? So you may have grabbed one that only had the Brussels show on it. Since most of the Brussels discs combine these shows, and often putting the songs in a random order, I know I always assume Heartbreaker was played (and recorded) on 10/17.
see urbansteel's Brussels discs, which show exactly where each song came from
here.Now, with all this information, the 9/9/73 show was compiled from the soundboard recording's and filled in with audience recordings
here. Here heartbreaker is called doo doo doo doo doo (which is what jagger calls it before the band starts playing)
and just because I think the 73 tour is my favorite group of recordings, I'd suggest you try out this
one too. which is 10/13 and 10/14 some soundboard and while the band was still in this peak.
Hope that clears things up- stones shows have never been as well organized on bootlegs as some other bands, with various versions of shows on vinyl and cd, chopped up, edits done, various quality, a TON of misinformation on the liner notes, incomplete shows, dropouts mid-song, etc. Thankfully, now there is a lot of compiling and organizing that has been done in the internet age, so you can avoid a lot of redundancy in your collection (and spend way less money than when these records/cds were only available by mail order or in mom-and-pop stores.)
If I'm wrong on any of these, please feel free to correct me. I spent a ton of time organizing my collection of live and studio stuff a while back and discovered just how much redundancy I had in my collection.
