Love of my life

[henrikhank]

Christus surrexit! I am practicing Love of my life by Queen on my piano. I really like this amazing song. In the intro of the song there is a trill. How would you play this trill? It seems that Freddie is using rubato when playing this. How would you use rubato when playing the song on piano? And how would you use music theory in order to learn this song?
