 Until the last thirty seconds of this two and a half minute dance the pair appear to pull back from touching, then with a crook of her elbow Rogers invites Astaire in.The routine, at once comic and romantic, incorporates hopping steps, tap spins with barrages, loping and dragging steps among its many innovative devices.The spirit of equality which pervades the dance is reflected in the masculinity of Rogers' clothes and in the friendly handshake they exchange at the end.
