It’s hard to tell, but probably not. I was a HUGE fan from their debut album “The Allman Brothers Band” which was released November 4, 1969 (I was a freshman in the Fall of ‘69). We got some big acts (Beach Boys, Three Dog Night [I think]) and when we had the Allman Brothers a couple years after their debut, they were already HUGELY popular.
I grew up in the New York City area. From the late 1980s through about 2010 the Allman Brothers used do a whole bunch of shows there every March — sometimes as many as 20 nights in the month — with such regularity that it almost became a ritual signaling the arrival of spring.
