This pairing of two Incredible String Band records from 1971 features principals Robin Williamson and Mike Heron with Rose Simpson and Licorice McKechnie. Be Glad for the Song Has No Ending, the first disc up, was issued in March of that year, but contained music from 1968 and 1969. It was also the last ISB recording produced by Joe Boyd. Boyd assembled this collection of leftover tracks from between the Wee Tam and I Looked Up offerings, with the intention of just getting the music out there. In fact, two cuts from the first half and all of the second half of the album were a soundtrack to Peter Neal's ISB documentary film of the same name -- the picture saw release in 1970, but was then shelved until its "rediscovery" in the mid-'90s and subsequent video release. The second half of Be Glad is all instrumental, composed no doubt as "incidental" or "serial" music.
