i've GOT to identify this music video, please help.

Okay, one of my Spanish Friends has sent me a music video that is quite easily one of the most ridiculous things I’ve ever seen. I just HAVE to identify the group and the name of the song. I hope someone here can help. The video is obviously from the late seventies early 80’s I am not sure if its video or film, its too grainy to tell. But deal is the video opens up on the band in a clearing in a forest. The lead singer plays these keyboards and is sort of playing them sideways looking at the camera. He’s got long brown hair with bangs, and wears sunglasses and has a huge moustache. He’s wearing this white cowboy outfit that has all of those tassles like they had back then. Then all of a sudden about a minute into the song. out come these three girls who are supposed to be indians? I don’t know, but they come out from behind these lame tepees and start fawing over the keyboard player. Later on there are some spoken words like " Great Warriors, Riders of the Plains" and somethign about “Free” but its spoken words, not something that is sung. And the guy saing this has a gruff voice. The keyboard player, however often interjects to get out a couple of Oooooh, that last an entire measure. The melody is familiar as it is obviously some old western song… I wish I knew how to find it but its pretty familiar from a movie somewhere, I think. Oh ,and the guy gets up and does a really lame dance with the girls…The video has the logo DR2 at the top. That’s Danish Television. I don’t know if they are European or not, though. Also the video has the website on it. I probably can’t post the name here, because it has pornography among other things. but it is your typical spanish humor website
anyway the title is called clip_friki.mpg Its not anywhere to be found on google

Please help me with this because this video is hilarioius
