Actually, encouraging Guests to join along in clapping the "hand jive" is part of the Hakuna Matata section of the show, which I believe comes after the Tumble Monkeys' acrobatic section. While there is alternate choreography for some sections of the show (like the afore-mentioned non-flying birds), if any section of the show weren't going to be performed at all (like the acrobatic trampoline section), they would have just skipped that section of the soundtrack entirely.
