Syd Barrett on record (Pink Floyd discography, part 3)

Syd Barrett's relatively brief recording career has been anthologized a few times.  Below is a roadmap to finding his work outside of Pink Floyd.

-His first two LPs, "The Madcap Laughs" and "Barrett," were released in 1970.  They were later compiled together as the double LP, "Syd Barrett" (1974).

-In 1988, EMI released a collection of outtakes, "Opel."

-In 1993, the boxed set "Crazy Diamond" compiled the three albums listed above, with 19 bonus cuts spread over the three disks.  A promotional 7" EP on pink vinyl (with picture sleeve) was also released.

-Later compilations include Octopus: The Best of Syd Barrett (1992), The Best of Syd Barrett: Wouldn't You Miss Me? (2001), An Introduction to Syd Barrett (2010, including his work with Pink Floyd).  New songs made available on those are:
"Bob Dylan Blues" [Wouldn't You Miss Me?/An Introduction]
"Matilda Mother" (Alternate version) [An Introduction -- also on the "Piper at the Gates of Dawn" 3-CD deluxe set, but remixed and extended here]
"Rhamadan" [An Introduction, iTunes bonus track]

-Mr. Barrett also appeared on the BBC twice, performing on Top Gear (John Peel's show) on Feb. 24, 1970 ("Terrapin," "Gigolo Aunt," "Baby Lemonade," "Effervescing Elephant," "Two of a Kind") and on Bob Harris' Sounds of the Seventies on Feb. 16, 1971 ("Baby Lemonade," "Dominoes," "Love Song").  All of these songs are on 2004's "The Radio One Sessions."  The Peel session only is on "The Peel Sessions" (1987).

-He plays guitar on "Religious Experience" (aka "Singing a Song in the Morning") recorded during sessions for the 1969 Kevin Ayers LP "Joy of a Toy."  The song would not be released until the 2003 CD reissue of the album.
