Yeeeaaoowwww!
I think Boston was the second Rock and Roll show I ever saw in my life, circa 1977 (?) & yes, I plead guilty- it was a teenager's high all the way.
First Rock and Roll show was, and I feel I can stretch it a bit, CAT STEVENS- tho he may not really qualify as R&R (especially now) I remember the sonics were amped so high my innards were vibrating.
