I once had to see a video of myself singing, and all I can remember thinking was "Right, THAT dress is going to that charity shop!" But yes, recording and listening to oneself is useful, even if a bit painful at times.

If you're only drifting up half a tone or so, just forget it, no one will notice. The real problem is the singers (and we all know at least one) who have no idea of sticking to a key at all, starting every line or verse in a different key and wondering why their hapless audience don't join in. It sounds as if you're a world away from that, Penny, so don't get too hung-up about it.
