Queen for a Day - More of that Jazz

I absolutely do not understand this song. First off, it sounds like a desperate John Lennon grab. But it's empty and soulless. Filler of the ultimate type. It does, however, hold fast to the Roger Taylor " bored and a rock star and I've got wayyyy too much time in my hands" aesthetic that he mined in "Drowse".
The riffing is pretty great then---
Suddenly the song lifts pieces of a majority of the other tracks and strings them together in a montage before heading back to its own chorus. Which is, "give us no more of that jazz". So...is he saying that the rest of the album is shite?
I don't know. I know that this song is a bad coda to the last "Me decade" album by Queen.

Grade: C-
