The Act seems to be a bit circuitous: it says that a "performance" is defined as "(a) A dramatic performance; (b) a musical performance", etc, but without saying when simply doing something becomes "performing" it. A session is often more like a rehearsal than a performance.

It could be argued that at a certain level (a family singing Happy Birthday; the Best Man's wedding speech; some friends singing carols together) there is no "performing" taking place, as there is no paying audience. Pub sessions are a bit of a marginal case, as there is often no real "audience" and no charge is made for listening in to what is essentially some informal music-making among friends. Sometimes it even takes place in a closed room where everyone is a participant - although I suppose it could become a "performance" as soon as the guy with the camera appears and starts recording. Sounds like a good reason to send him away.
