Sliver-Sucker (clarinetist) Benny Goodman, and Skin-Beater (drummer) Gene Krupa get in the groove (hit their stride) at a jam session (musicians playing for their own amusement) after working hours. 

 Big Apple dancers will swing it anywhere, even if the music is nothing more than corn-on-the-cob (a harmonica) and a belly fiddle (guitar).

This is the Little Apple, a miniature version of the dance [above], and you don’t even have to leave home to do it if you have a platter (a record) made by hepcats (swing musicians). 

There’s nothing long-haired (symphonic) about it when Scat-Singer Leo Watson and Trumpeter Charlie Frankhouser swing it with Gene Krupa’s band. 

Bogie men (critics who say what they think) call Herb Haymer of Jimmy Dorsey’s band one of the world’s best on a gobble pipe (saxophone).
