In answer to OP’s question regards Freebird becoming a cliche, the answer is mostly geographical. I was in a serious traditional blues band and we’d get booked into pool halls and bars and such and invariably as we were setting up there would always be a couple young Johnny Rebs easing up to the stage and the question was always the same, “what kinda skin-nerd you got for us tonight?”, then as soon as the first note was struck for sound check until we’d start tearing down later, every few minutes someone would call out, “Freebird! Yeahhhhh!!”. It may have become trite simply from the number of times it’s asked for in the joints down here. We never did learn Freebird but we did add faithful renditions of Simple Man, The Ballad of Curtis Loew and Mississippi Kid and would usually close the night with Whipping Post and One Way Out The BL’s mission was to bring them to the alter of the blues (his words), if that meant showing them the roots of the blues in their beloved sudden rock, so be it.
Whenever my brother puts together a band for a private or frat party, a Ska version of Sweet Home Alabama, covers of Barefoot Jerry, the CDB, Grinderswitch, White Witch and many other bands from the southern rock genre are subject to be on the setlist, and he came up in the height of the SR rise from regional thing to the near national hysteria that generated such cliches as Molly Hatchet. Needless to say he considers himself a serious musician so while he grew up loving the genre, he’s by it in general like I am by Stairway To Heaven, it was great the first 987,653,464,925,301 times i heard it; these days, not so much. I won’t quit a band that starts wanting to do the sudden rock thing when it started as country, or has members who think southern rock has any roots at all in country music, but i will start looking the harder they push it. I’m old enough to remember being ragged by my country loving friends for listening to “that hippie poopie” so the whole SR has roots in country is a marketing gimmick that has been embraced by the generations too young to have experienced having to fight your way out of a bar for playing a Charlie Daniels tune on the jukebox.
