Our pack also sings. From our cubmaster who encourages audience participation - yes even from the parents; to the dens, especially one with a den leader with a guitar. Most of the time it is done without instruments.
My favorite is "Baby Shark". Don't know if that is the correct title, but it is fun and easy for others to pick up on the words as there are only a few. The cubmaster has a few songs always ready to go in case there is need for a filler. Sometimes they are actually scheduled in the agenda.
