Member of the Whitey’s Lindy Hoppers, Ann Johnson was seriously badass (you can see her undies – and hardcore leg muscles – here. She and her partner (Billy Williams) are the first onto the floor in the jitterbug contest section of the ‘Keep Punchin” short (at about 3.08 in this clip):
She and her partner (Frankie Manning) are the fourth couple in the Hellzapoppin’ sequence (at about 3:59 in this clip):
Props to Bobby White for listing all the dancers in his post on iconic dance clips. There are lots of women dancers that I really want to list, but who aren’t identified in the footage!
Edit: I’m going to try to add all the clips featuring a dancer I can find to each of these posts. Try.
