I just found out about this band that plays locally, called "The Chardon Polka Band", here they're playing their song "Free Beer Polka"... no harp, but get out your G harp in 1st (great tongue blocking chord practice), or your C harp in 2nd, also great if you have a G or C echo harp (try them all) to play along to... I enjoyed it, but I also like many different musical things... I remember having lots of fun drinking beer to polka music and also square dancing !
