Here's some classic polka from some snappy dressers (kidding, folks...what else could polka bands really wear in the 70s?). Originating in Edmonton, Alberta, the Emeralds have had a long career.
This band still exists in 2008, and have a very good website. To steal a little text from their site, here's a quick history:
"The group has entertained internationally in New Zealand, Australia, Singapore, Hong Kong, London, Trinidad, the United States, and Canada. The Emeralds have recorded 29 albums, including their latest release "Look At Us", resulting in 6 gold, 2 platinum, and 1 double platinum award. In 1997, The Emeralds were inducted into the City of Edmonton's Cultural Hall of Fame. The Emeralds are Internationally Acclaimed Gold & Platinum Recipients and are the band behind the International Hit "The Bird Dance". The Bird Dance is featured in the Paramount Pictures motion picture Jimmy Neutron: Boy Genius."
This LP came out in 1985, and contains a series of polka medleys, all of which show some good fun and exhuberence. I'll offer one such medley here, that contains Hail Hail, I've Been Working on the Railroad, and everyone's polka favourite: EIEIO.
