I bought this at Madison Square Garden at the 9/22/76 show.

I went for Springsteen but Tom Petty was great and James Taylor and Carly Simon did "Mockingbird" together.

Jackson Browne did a set too.  (Looks like the graphic wasn't up to date)

CSN was also a treat...especially from the 3rd row with 20,000 fans behind us!

I've never worn this one and I wouldn't fit now if I tried!

No tags (ever) so I'm guessing at the size.  Definitely cotton. Pristine condition.
