Southwest airlines posted a fun clip of a band (the Black Cadillacs) performing a song they wrote in Memphis, in a 737 flying to Memphis. The plane's public address system provides far from a perfect sound environment, but the passengers seem to be enjoying it and it seems a fun experience!
Anyone ever heard a concert while flying? Only thing I was ever treated to was a nice version of 'Happy Birthday to You' (and not to me -- to someone else).
