Sorry if I seem thick here, Gord. I've got a small bit of experience here, and most of it was done wrong, so I am desperately trying to figure out some of the underlying concepts rather than performing canned patter!
I am going to try to restrict my perfromances to 6-12 years old (generally speaking - I know younger and older show up to kids parties). I'm trying to put shows together that are applicable to the age group (another thing I did wrong before).
For a children's show it is important to set the rules right off the bat, but in a fun way. Get them clapping and laughing. Tell them you need helpers and show them HOW to volunteer.
I can see this working for maybe up to 8 year olds. But by the time they're hitting 4th-5th grade, do they still want the silly stuff?
I then recommend that the first trick include a volunteer, this shows the other children that you are not going to embarrass them and that you can be a lot of fun.
I was once told by someone else NOT to use a volunteer right out of the chute, because the kids don't know what they're getting into with me yet, and I run the risk of getting either a child who is pushed up there and will freeze or one who takes the opportunity to hijack the show!
I think for me I would rather use the first routine to establish myself while allowing them to participate from where they are sitting down. It also gives me the opportunity to gather my confidence and know we're all going to have a good time. I know that will change as I perform more and gain proficiency; until then, though, an initial success does wonders for me!
Then go into the Vanishing Bandana (Banana). It's a fun routine, it makes them laugh, it's got great magic and comedy. It is also so strong that odds are it will be the one trick remembered by the majority. Placing it second gives you a good chance of having something else remembered as well.
Hope it helps.
What age groups would you use this for? If this is so strong, would it be better placed later to erase any memory of weaker routines (especially in my case!)?
I hope I don't run you out of patience! If you can recommend a couple of good books dealing with this kind of "theory of routining", I would appreciate it. I've got "Seriously Silly", and regularly check out from the library Hay's "Amateur Magician's Handbook" and Mulholland's "Book of Magic".
