My friend Tore from Göteborg was visiting our session in Stockholm yesterday, and told me of this brilliant idea that he had come up with:
Print the names of session tunes common in your area randomly on 5x5 grids, and then distribute these among the session participants (and any interested listeners). Then you cross tunes off as they are played, and the first person to get 5 in a row shouts "bingo" and wins! One extra rule is needed: You cannot start a tune which is on your own grid.
Would add an extra dimension to your local session, wouldn’t it? :-)
