Years ago, at the old Bank Street Café, there was a multi-band bill of local acts performing on a Friday night.

One band took the stage and were execrably awful. I’m not sure I’ve ever seen a group as bad. At the end of the third song, the guy next to me, whom I didn’t know, took a sip of his longneck and said to no one in particular, “It’s the Allman Brothers at Fillmore East.”

I STILL laugh when I think of that line. Anyone who’s ever heard the double live album “At Fillmore East” by, yes, the Allman Brothers Band, pretty much agrees it’s the greatest in-concert recording ever made. So, the dude’s laconic observation was the height of understated brilliance.

My point? On Saturday, a tribute band called Live at the Fillmore East appears at The Kate in Old Saybrook, and their night-after-night mission is to recreate the sounds of that immortal Allman Brothers Fillmore residency.

I’d better not show up and see that band from Bank Street Café.

Live at the Fillmore, 8 p.m. Saturday, The Kate, 300 Main St., Old Saybrook; $38; (860) 510-0453, www.thekate.org.
