Just wondering, as I have an obsession with Syd and the Floyd. I've got most of Pink Floyd's albums including the Piper at the Gates of Dawn, Relics, A Saucerful of Secrets, and I've got the Madcap Laughs, Barrett and Opel by Syd. Can anyone name a few very early Pink Floyd/Syd Barrett songs that didn't appear on any of these albums, but that I mite be able to download?
As for early songs that were never released or only played live: Vegetable Man Lucy Leave King Bee Sunshine Scream thy Last Sceam Stoned Alone Candy and a Currant Bun(it is out there, was officialy released, hard to find) Reaction in G One in a Million She's a Millionaire Rooftop in a Thunderstorm Row missing the point. Then there's plenty of live versions of songs such as Flaming and Matilda Mother that are out there and awesome. Well that's about it for Syd era stuff that you might be able to find.
