Travel Channel - Song Question

Lately, the Discovery networks have been playing ads for their Discovery Travel channel. The ads show a group of yound people dirtboarding down what looks like a slope in the alps. While they are doing it, there is a folk song in the background that is being sung in English with a strange, possibly Scandanavian-American accent. The song is very hard to understand and the only lines I can make out are ‘one for me and one for you’ and ‘yours if it lands in the clover.’

Does anyone have any idea what the song is and what it’s about?
