As Dana mentioned on the podcast the performance was taped and is on YouTube.
Dana says you can see him wearing a black suit (with no hat) slow dancing with his wife during the first slow song.
I will send a brand new penny to whomever finds him... winner must pay shipping.
EDIT: I am astonished to report that eagle eyed reader "I'm That Jon" actually found Dana in the video.
I am also happy to report that "eagle eyed" is a comment about his ability to spot small details, rather than a terrible ocular defect.
You are a winner sir! In order to claim your prize simply write your name and address on your computer screen in black sharpie. Make sure the blog is open so I can see it.
Then stick $3 shipping (plus 1 cent handling) into your CD-ROM drive or USB port and the penny will be sent ASAP!
