DCMS Q: How do you define public entertainment?
DCMS A: In broad terms, public entertainment is music or dancing, or entertainment of a like kind, which is presented publicly for commercial purposes or for gain.

'Public entertainment': as musicians & singers, we're not intending to entertain others (are we?), but we are performing to please ourselves.

'presented publicly for commercial purposes or for gain': sessions / singarounds are not for commercial purposes, nor are they for gain (other than for our own enjoyment).

Does this mean we're exempt? Or hass the beer I've just been drinking made me look at the situation through rose-tinted spectacles?
