What is the name of the song that plays on the Guinness advert? It features people running through a wooded area following some moth like insects and then finding a pub!! The music sounds like it is ragtime perhaps from the 1920's or 30's
It's the 'swing' classic called 'Sing, Sing, Sing' written by Louis Prima in 1936 (not the 1950's as the Guinness site says I believe) Benny Goodman had the hit with it - and it's his version taken from the film 'Swing Kids'.
