A St. Valentine's Day special, featuring Billie Holiday and an all-star cast of players, most notably, imo, Lester Young (check out his solo at the 2:00 mark). Not to downgrade the rest of the players at all- Coleman Hawkins two solos are as dandy as it gets- but the heat generated between Lady Day and Pres is palpable.
