firends of mine run an excellent one in Sydney every week....... it is as part of a proper session, but they designate the first hour to be a "slow" jam where things are played slowly, a new tune is introduced every few weeks, and gradually people get to know them......

Celtic music slow jam at Hornsby

works really well, and the tunes are incorporated into the "faster session"...... great for building up people's repertoires and confidence
