If I went UFO I would go with Lights Out but Rock Bottom is good too.
Definitely gotta do Stealin' by Uriah Heap.
An interesting one that I have seen work well in bars is The Safety Dance - Men without Hats
Any SRV will always work.
I like The Who Love Reign O'er Me, one of my all time fav's but probably hard to do in the bar scene. Maybe Baba O'riley or something in that genre would work better.
