One suspects there'd be more chance of finding byzanium in the wild than discovering the original session tapes of RTT
Such a shame that so many of Barry's scores were for small indie companies that went under (pun intended), leaving the tapes in either legal of physical limbo. Whereas John Williams, for example, was lucky enough to work almost exclusively for big studios which generally still have the tapes of even his most obscure scores.
Went back and listened to the rerecording, in the wake (!) of this thread. I've never seen the movie, so never heard the original recordings; no grounds for comparison for me. That said, though, Raine's work with the Prague SO is delightful. If the original recording ARE found someday, that'll just be a bonus.
