With so little material available, it's common for outtakes and assorted ephemera to be released to a ravenous horde of uncritical fans. These are interesting but non-essential releases. The Rykodisc release serves as the most exhaustive and authoritative document. Caveat Emptor: Let There Be Burma
is a re-release of Mission of Burma
(not to be confused with the Rykodisc release) and Forget
on one disc.
