It's a simple solution: the band needs to look like you're having fun.
Face the crowd, sing along with the song off mic, move in time with the song, look at the other musicians with a big stupid grin like you're having the time of your life and there's no where else you'd rather be right then.
The audience will follow right along.
Edit: my classic rock cover band is pretty good at this, I'll try to get some video from tonight's gig and post it here.
