tracks 01-06: superb soundboard, directly from the King Biscuit Flower Hour transcription radio show LP or reel. The most known JW radio show from this era. Absolutely killer versions!
tracks 07-09: excellent FM recording. No exact date on this one, although all traders list it as 1978, it's from the European tour in April & May 1979. a DJ, with a British accent, says it's "British Biscuit" radio show. .
