I did this show many years ago for zero pay. I was probably not their first choice but I was young & up for a challenge.
When I got there, there was a big problem. I don't read & the bass pad was all notation. I noticed the guitar pad had chords above the notation so introduced myself to the guitarist & sat down next to him very close, much to his surprise.
I then did the rehearsals & a weeks shows reading the chords from the guitar pad and looking at the bass pad to see if the notes ascended, descended, etc.
I got away with it but I'm sure you'll do a far better job of it than I did.
