The band made a tour of Japan in 1972 that resulted in this live album. Originally intended as a Japan-only release, its worldwide release made it an instant hit. It remains one of rock music's most popular and highest selling live-concert recordings(wikipedia). Link in comments.
This was book 18 in the Biggles saga and was written in 1939. Michael Palin recorded the audiobook in 1997 and did a fine job. I believe he previously portrayed Biggles in Monty Python's Flying Circus with reference to BIGGLES FLIES UNDONE. Link in comments.
The remaining Monty Python members did these interviews for the BBC in promotion of their live show ONE DOWN - FIVE TO GO. The show was a success. These interviews might be the last time we hear from Monty Python's Flying Circus. Link in comments.
