I like Peter T.s suggestion of hooking to video and playing the live music on the monitors. Ive seen it done in a Irish session in London. It was more a performance than session I should say as they were miked as well and werent open to other players.

The One true Irish Pub in vancouver bc. (The Irish Heather) has no tv monitors, although other pubs do, usually the sound is turned down, but its still irritating. Petr.
