A Strange Request

[Durin]

For my government project, we have to make a music video with a song that everyone knows. I figure everyone would know "We Are the Champions" by Queen. I've found some decent instrumental tracks to use but all of them have the vocal harmonies and I figure that'll create some clash with the lyrics.

 So I was curious if anyone knew some places to find instrumental versions of popular songs, or had anything that could help me to get the track. I don't mind the harmonies themselves, but the fact that the lyrics are there create worry.
