I would love know if you have The Dead's Capital Theater show of 1980-03-30.  John Belushi came out and performed 'US Blues" in full Blues Brothers regalla.

It was my first real concert at then age 14.  I was with my dad.  During the show my dad would get up from our seat and go a couple of rows back to "smoke".   After the show we stopped at a dinner on route 3 in Nutley, NJ for something to eat.  After putting 2 and 2 together it took me a few years to realize that my father wasnt smoking Marlboros that night.

The set list includeds: Set1: Alabama Getaway > Promised Land, Peggy-O, Cassidy, Loser > El Paso, Far From Me, Tennessee Jed, Minglewood Blues, Althea, Lost Sailor > Saint Of Circumstance - Set 2: Scarlet Begonias > Fire On The Mountain, Estimated Prophet > Eyes Of The World > Drums > Black Peter > Sugar Magnolia  - Encore: U.S. Blues with John Belushi
