I found some rare Woodstock stuff showing Alvin.
Look here (at 3:26):
And there's the Woodstock Project:
scroll down to Disc #20 and read:
Ten Years After:
11. I Can't Keep From Crying Sometimes Source: A27
12. Help Me Source: A27
13. I'm Going Home Source: Directors Cut, Box Set
If someone is able to download that stuff (by torrent and just only 26 CDs complete) I'd be very pleased to be informed and get the TYA part somehow.
Should be shared with all of us anyway, shouldn't it?
