My friends and I would form a group and create musical instuments from scraps. We'd ask for aluminum bottle caps to the store nearest to our house. Then we'd make the aluminum bottle caps that we've collected the flat as possible, make a hole in the midddle, and put a wire between it and make it as circular as possible. And we'd walk for miles going to ecery houses we'd spot and sing . After the owners would provide us money for us to keep and out at the of the night.
