Once the idea for this recording came up, we did supply 'stems' of our own original backing track to the Muppets, so that they could effectively 'sing' with Queen. We don't often do this - it's only because of our respect for these people as artists that we'd do this. I'm sure Freddie would feel the same way ... some projects are just worthy of a proper collaboration. So .. yes .. you are hearing us play on this track - including Freddie's magnificent piano track, of course. I think it makes it all the more funny! After they'd done their bits we got the track back to OK ... I immediately thought it was brilliantly done, but I had no idea it would light such a huge bush fire. Amazing.
