Last weekend Dean & Britta played a "Dean Wareham plays Galaxie 500" show at the Forecastle Festival in Louisville, KY, Dean also turned up in My Morning Jacket's headline performance joining them for a cover of George Harrison's Isn't It a Pity - a video of the whole 2 hour set has turned up on YouTube, Dean turns up about 38 minutes in.

The excellent You Ain't No Picasso has a great picture as well as an mp3 of the track - you can also download audio of the whole show (as ripped from the webcast) from The Steam Engine.

There are also a couple of nice videos from Dean & Britta's own set:
