2. Ask the band if they do any of the songs differently from the recordings. Do they do a song in a different key, is there an added chorus, is the whole song played with a different feel, etc... I recently had to learn a CCR song. Nothing hard, but I took a good 20 minutes to get it down. I showed up to rehearsal only to find out the band plays it nothing like the original, so I had wasted my time even bothering with the song.
The band wants to meet up at a bar and chat with me next week (to size me up? Haha who knows), but this will be one of the first things I ask.
I am taking someone's advice about transposing the songs to Nashville Numbers, that way if they play it in a different key, it will be simple transposition.

Guess I'll never be a real bassist...
