What is the classical tune (strings) played in the background in the SATC episode "catch 38" when Carrie and Alexander plays with baby Brady(and painting) in his apartment? This tune is also featured in The Simpsons, the episode when Santa´s little helper runs away (and is seen as a "dot" on a map chasing a cat), also in the episode of Krusty´s Comeback special when (I think) Hugh Hefner "plays" the tune on wineglasses. Thanks!
