Hey man, I think if I could offer you any advice at all for a cover it'd be go for the most popular track you can. It can sound pretty boring just picking a really well known track, but you can have some fun in how you choose to play it.

I play in a Jovi tribute band and it's sadly the case that you can play a less well know track really well and get a lukewarm response because it wasn't a big track - or a massive hit less well and get a lot of crowd interaction and a great response. Sad but true.

Be cool to see/hear some of your band stuff if you get any recorded.
