After checking out the songs in your chart, it looks like the majority of them are fairly simple songs. The chord progressions don't look too complex, and some of them, like Folsom Prison Blues and Johnny B Good, are really simple. If the bandleader has given you the option of picking your own songs, then pick a couple of simple ones so you can get warmed up, then a couple of more complex ones to show off your bass-playing chops. Remember, simple lines and lock in with the drummer, that'll carry the day for you! Good luck!
