From the movie White Christmas. Judy (Vera-Ellen) and Betty Haynes (Rosemary Clooney) are a touring sister act performing at Novello's in Florid. Across town the famous Wallace and Davis are performing their new revue Playing Around.
The sisters perform their song Sisters with a smitten Wallace and Davis in attendance for the show. It seems the sisters' brother Bennie Haynes (Carl 'Alfalfa' Switzer) had asked the world famous performers to check out his sisters' act. However Bennie didn't ask, Judy Haynes forged a letter from her brother to lure the guys to the show.
