How do you get a tune out of this?

This is Legograndma; she's 80 and still in good health. Her activities include ballroom dancing (she did another dancing exam only the other week) and painting. Quite a few of her pictures decorate the commune walls. My Grandparents, Mrs. Legodude and myself were invited to dinner by some friends of mine who I've known for years and now live in Low Bentham - not far from Sedbergh. They have a didgeridoo that my Gran couldn't resist trying out. She has the honour of being the first relative I've ever blipped!
