I attend around 3 open mics a month: I usually favour the quieter ones as often I'm the only Bass player so stay on all night...! My heart often sinks as yet another singer songwriter get ups, declines my bass accompaniment and bores me rigid for 20 minutes! The best one has just been knocked on the head however, just me and the guy who ran it, he'd flick through his book of songs, ask if I knew it, I always said yes and then just read it off his chord chart if I didn't actually know it. We'd always have to finish with "The Chain", just me, an acoustic guitar and him with a Vocaliser. Happy Days ( which incidentally we never did)....
