We're presently working out a set for our group (The Daub'z...) for a gig mid-June. For various reasons, we've not been playing, nor even meeting up, for over two years. We've drawn up a list of songs to go into the hour-and-a-bit set from past repertoires, including SOAD, RATM, Nirvana, Pink Floyd, Noir Désir, RHCP and many more. There are fifty or so on the list; we'll choose about fifteen or so. All of us can play any or all of these, no sweat, on demand. None of us use any support at all, neither tab, notation, recordings... They're all played solely from memory, having rehearsed them in the (sometimes distant...) past. For my part (on drums...), I've a fifty-year long repertoire of variety stuff and dance music, with songs spanning well over a century, which I played intensely for several years as a pro drummer. Believe me when I say that some of it sticks..! All in all, 200+ doesn't seem that unusual to me; if we, as a very amateur group, can collectively call up fifty or so, any half-serious player could easily beat that, as long as they've had exposure to a fairly varied repertoire over a reasonable length of time. Nothing unusual in that, for me.
