While I have covered some boards with tape on multi band shows, at this point I think I can grab any fader on a standard 4-8 piece rock band without looking if I am allowed to patch my way. Any oddballs end up in the same places also so all I typically have to do is look for what is not standard on stage and I know where it will fall on the board.
Bands seem to think they are doing me a favor by sharing mics, as if it is a great imposition to set up a mic and channel. If you need a mic for one song because the rhythm guitarist is going to play a xylophone, just ask and I will set it up at his playing position. No need to try and drag the SR vocal mic to SL and then adjust levels and then drag it back when you are done and readjust. Same thing for guest musicians band members invite on stage.
I think with digital recall people are forgetting that the reason some shows went to high channels counts on analog was simply to have things ready for a single part of the show.
