Hey, I stand corrected, you are 100% right,  in fact I found my ticket stub for the Allman Bros show, I also taped it that night and have still, and IT was the very first concert there.  The Who on the 6th was obviously the second.  As for the Largo, Landover identity, both were used in ads and throughout the years as the address of the Capitol Center as those two little towns are right together and the Cap Center was on the line.  Either one was really correct.  Love the ad you posted, what other shows did it show coming.

I copied The Who ad while in college two decades ago.  I can't remember what other bands were mentioned, except Alice Cooper on Dec 19th.  I only knew about the Allman Bros. as it was mentioned in the Who concert review.  The photo insert that came with the Odds & Sods album is taken from this show.
