Saw these guys a couple weeks ago, very expensive tickets, the most I ever spent, and I've been attending rock & roll concerts for close-to 55 years.
The very first live performer I saw was during my time in what's now called 'middle school,' it was a concert in Rochester NY and Leslie Gore played. It was when she was very popular, "It's my party (and I'll cry if I want-to)," "Judy's turn to cry," and probably my favorite song of hers, feminism before there was that word, I believe, "You don't own me." She might have lip-synched, for all I know, it was very entertaining, though. With older brothers, I was exposed to the gamut of early rock & roll, and the folk-song time a bit later. I was in jr. high school when the Beatles and the British Invasion hit, and I still have my original LP copies of Between the Buttons and Rubber Soul, and a picture-sleeve 45 of "I saw her standing there" and "I wanna hold your hand." In 1964, the Beatles held the #1 position in the United Kingdom for 40 weeks. And this summer is the 50th anniversary of my favorite rock album of all-time, "Sgt. Pepper's Lonely Hearts Club Band."
Speaking of ZZ Top, I once saw them open for Eric Clapton in West Palm Beach at the dragstrip there. It caused a horrendous traffic jam, and we had to walk miles to get in. People were abandoning all the stuff they were carrying, it looked like the rout of an army-coolers, tents, lawn chairs, clothing, just left on the sides of the road, Beeline Hwy, not too-far from the Everglades. Appropriately we got close to the concert in a VW bus.
