Freddie Mercury F#6 and D6 in Dragon attack, highest note?

Hey yall, I'm a lurker on this forum but i decided to post today. I was listening to Dragon Attack when I heard a very faint shriek from Freddie and it was pretty high. So I pulled up an isolation of the bass and Freddie's vocals of the same song and around 0:32 you hear a D6 from Freddie after john finishes his riff. Then around 4:05 Freddie hits what appears to be a F#6. Is this his highest note? Ive heard of the F6s and D6s at tokyo 79 and the crazy tour and even the F6 at london 84 but apparently he hits some high stuff in the It's Late Maida Vale version. Listening to 2/16/1981 on Ryan Newtons channel I hear a CLEAN D6 at 28:15 and what sounds like an E7 at 27:19 what sounds like an E7... idk about the latter one. I just want to know what's Freddie's highest known note and possibly lowest known note.
