Under Pressure: Best Rock Duet of All Time?

When Queen and David Bowie came together to create "Under Pressure" the world received what is, I think, the best rock duet of all time. After all, the song features just about the best bass line of all time plus the dueling vocals of Freddie Mercury and David Bowie. It really doesn't get more Glam than that.

I never saw Queen with Mercury (or without for that matter) and I've never been to a Bowie concert either. Apparently Bowie does "Under Pressure" at every live show - I think that would be epic! There's something about the riff of the song...you hear it one time, and it's all over: the song owns you!

"Under Pressure" is a great duet because it's all rock and no sap. A nice, deep hook and great vocals equal a classic tune.

Can you think of a better rock duet?
