Songleading? Performing? Singers have 'performance' built into them, particularly those who do so unaccompanied. This is evidenced all too often by calls for 'hush' by the high priest/ess of the gathering, dagger looks if one dares to join in (let alone add suitable accompaniment), and applause after each 'performance', warranted or not.

Give me a good Session anytime, with its minimalist approach to applause and such like: the players are more likely at the end of a set to simply reach for their pints and resume their chat. At most, a quiet "hmmm .... nice tune" will suffice.

I'll get my coat!
