See Soft Machine live on French television in 1967 (from "Dim Dam Dom"). I found this info on "What's Rattlin'", where I also found a link to Invisibop's version av "Moon in June".
Rachel Unthank and The Winterset's version of "Sea Song" (Wyatt) is on the CD you get when buying the last issue of "Songlines".
According to Une Discographie de Robert Wyatt Eyes Like Saucers also do a cover version of "Sea Song" (not on MySpace). I haven't heard that one. Anybody else?
