Here is what he said:

“Happy birthday to one of my all-time favorite rock n roll hero’s…

Steven Tyler, photo by Ron Pownall. #1975.”

And here is how Ron Pownall celebrated Steven’s birthday:

“Today is Steven Tyler’s Birthday. Happy Birthday, Steven! I first met Aerosmith in 1973 at the Roberts Center at Boston College. It was a-rockin’ gig in the gym for a campus Fall Festival of some sort. (If I’m not mistaken, the band canceled a gig opening for Mott The Hoople in NY so that they could headline at BC… I’d love verification on that). Hey, a few bucks is a few bucks, right!

These pix are from a CREEMmag series, “Stars Cars,” in 1975. We shot around Jamaica Pond, on the edge of Boston. Everybody in the band had these fancy Porsches, ‘Vettes, “Z’s,” but Steven had a barely-running 1956 Mercedes 220 Convertible. In fact, it died at the end of the shoot, and we had to have it towed; despite Steve’s insistence, we could figure it out because he had the owner’s manual! But, as always, we had a fun shoot.”
