Terrapin

"Terrapin" is a cover song by The Smashing Pumpkins off of Syd Barrett's debut solo album, The Madcap Laughs. It first appeared on the Dutch and UK vinyl editions of the "I Am One" single, and later on Rarities and B-Sides. Some commercial bootlegs incorrectly title the song "Crystal Blue" or "The Fishes".

The recording features prominent vocals by James Iha during the verses, with Corgan on backups and guitar.
