I am a guitarist. my brother is a bassist. we are both going to go to texas in a week, and we need to learn some songs.

These people are at a tractor show, mostly older people.

Any recomendations are nice.

I mean, the easyer, the better.

Through the fire and the flams by dragonforce is pretty much the easiest song ever

And old peole like that country group, Slayer

Probably 60's and 70's music... Beatles? "Take Me Home Country Roads - John Denver" might be good, it's a little country, great guitar though. "Drift Away - Dobie Gray" is a classic and is a song that everyone probably knows.
