Lucy, good advice from Boab. Watch and listen, unless you are an experienced performer. It is not a silly idea to get a feel for the type of stuff others do, and then try not to sing 'their' songs.

If someone sings your entire repetoire, you could always ask them to duet with you. "Give me a few pointers" is very flattering!

Go for it, girl. It is likely Reading is like most clubs, very supportive.
