The English wave of '64 and on were not only influenced by Elvis a "no show" but rock acts they could actually go and see. Bill Hailey was followed by Buddy Holly, Eddie Cochran, Gene Vincent, etc. You have got to remember Elvis never went to England to perform.
No offense to Elvis, but he'd never be able to match up with Freddie's range. Kind of shows you the vocal abilities of the Emperor of Rock.
Freddie purposely does an "Elvis impression" here, and to this day, some people think it is Elvis singing. According to Hince, the two of them then raced over to Musicland Studios so Freddie could get it down before he lost it. His longtime roadie Peter (Ratty) Hince, confirms this story as he was there in the hotel room in Germany when Freddie came out of the bath and asked for a guitar to finish working out the melody.
