Hallo Gunhild!
Happy some groove still came through 
Thank you for your kind words.
I have loved Queen since my childhood too and it was probably my least guilty pleasure music-wise over the years. And I still enjoy them. Sadly I was too young to ever see Freddie Mercury in concert. I still had the pleasure to see Brian May and Roger Taylor perform.
I see you are a super fan and even have the Red Special. Must be a different beast to tame if it plays close to the original 
I was surprised to find this song in Justin’s beginner book 2. This really helped to have the most important information for a “beginner” version on paper to fall back on.
The introduction even says: “This Queen song is unusually beginner-friendly”
With that said, as far as I understand it’s around Grade 2 Module 11 where Sus chords are introduced. By that time the power chord and the one F is something one can start to try and introduce into song practice already.
Reading your intro post, I read you already learned the rudiments of the song, have the books, and are already musically experienced.
So I bet you can move this song to your developer list sooner than you think 
“Liebe Grüsse” and keep on Rocking on 
) song still is much too advanced for me, but it keeps me motivated, and after a few weeks of practice I’d been able to play the main chords and these instantly recognizeable sus-chords at the beginning.
