There were a couple of one day festival type things held on various farms around central NC. Noon to Moon in Benson is the only one I remember by name, but there was another one held down near Kinston somewhere. That was just a way to kill a Saturday in the summer I guess ... and it almost always involved at least one of the Southern Rock standard bearers (Molly Hatchet, Blackfoot, Outlaws, Marshall Tucker, etc), a B List blues legend type (Johnny Winter and Sonny Terry come to mind) and the local touring bands (Arrogance, Nantucket or PKM depending on the year, Fabulous Knobs or Woods depending on the year, Glass Moon, Let's Active, Spongetones, Fetchin' Boots, Treva Spontaine, dBs, etc). Those generally involved a Coleman cooler filled with beer ... and lunch if you were smart ... and a bad sunburn.I can't really recall, but the mention of Molly Hatchet made me think back to seeing them in a farm field somewhere near Raleigh, maybe in 1979 because I was there w/ my h/s / college gf. I can remember that, it was sunny, and a Coleman cooler. That's it!
And no to Zep. My first proper rock show was ELO in Greensboro in 76. Zeppelin was sufficiently notorious that I'd have never gotten away with it. My parents were pretty slack and trusting, but only to a point.
