Guest 999 - thank you for your comment. Sometimes I feel like packing it in, but I keep trundling along, and every little bit of encouragement helps.

Getting down to practicalities for "Like a complete unknown," you will need about six songs for a half hour spot, and around ten for a 45 minute spot - so two 45's equal about 20 songs. Depends on the length of your songs of course, but most of mine are about 3-4 minutes long, and I don't mind running over a wee bit. Always keep one in reserve in case you're asked for an encore.
