B.O.C. was the first concert I went to, it was the Secret Treaties tour and I was in the eighth grade. (My parents let me go with a couple of older guys that were in my Boy Scout troop...) It was the early 70's (late '73 or early'74) so about the only thing I remember, besides sneaking down to the floor from our nose-bleed seats after the opening act, was all the band members donning guitars for 'Buck's Boogie'. Good times...
