A twofer. The first is a version of the much recorded Cole Porter "Begin the Beguine" by Bing Crosby, a singer not seen here before, I think. The second is a video of Fred Astaire and Eleanor Powell dancing to an instrumental version of the song from the film "Broadway Melody" (1940).
Incidentally the beguine is a dance that originated in the caribbean island of Martinque. That fact gives some idea of the cleverness found in Porter's lyrics.
Btw, since we are on the subject of dance, did you know the Tango is alleged to have originated in the brothels of Buenos Aires? This claim is much disputed and does cause one to ponder, since brothels main activity doesn't seem to be dancing. Interesting theory nonetheless.
