HI Geoff! Congrats on your Beauty and the Beast JR with casts of thousands! I love the inclusion, and quite honestly did many of the original pilots with casts of 160. If you are set on a Disney show, one of the most successful ones to expand is JUngle Book Kids. It only lasts 40 minutes but is easily cast with large groups that are not gender specific. If you need a longer show, look at Aladdin. Townspeople, shop owners, harem girls, guards and narrators etc. are featured in all of the production numbers. You might also take a look at Music Man JR and Guys and Dolls from our legacy series. Classic shows with wonderful parts to share with a large cast. Lets get you perusals to see what you think!
