well the title says it most. but the big problem is that im playing bass guitar(they kinda forced me into this) .So wich song should i play?

sory for bad english and if i didnt post in the right forum
If you're not very good at bass, just play a tune everyone knows but is quite easy, like 'Smells Like Teen Spirit' or something.. also, just for future reference, ain't one to nag, but you should have had your decision down way before now, never mind knowing how to play what you're gonna play. It can be the most simple song in the world but you've still got a chance of mucking up on song structure if it's not like, your most favourite song in the world. This is coming from someone who's been in your position.
Obviously it can't be any important performance if your asking what song to play the day before.

Anyways as to the OT, play this! http://www.youtube.com/watch?v=lH9-FFvup-4
