Found another great source for this show on dimeadozen: http://www.dimeadozen.org/torrents-details.php?id=3D272574
"Here's another one migrated over from another tracker. An old friend of mine made many great audience recordings in the 70's and 80's, and his masters are just now finding circulation. I have seeded my own transfers of 1st or 2nd gen copies of some of his shows, but his fresh transfers are massive upgrades. I couldn't help bringing this one over to Dime, today being the show's 31st anniversary. Enjoy. The GRATEFUL DEAD Live at the Winterland Ballroom San Francisco, California Sunday =96 October 22, 1978 Recorded by: Mike Martin and Mark Bunton.
