Ok I’ll bite! Who is John Deacon?
He is the bass player for Queen, so there are two in Queen who resemble Sir Isaac Newton (in my opinion), and both are intelligent and have scientific interests.
Per Wikipedia:
“He became interested in electronics, reading magazines on the subject and building small devices, including the modification of a reel-to-reel tape deck to record music directly from the radio. He studied well and achieved 8 GCE O level and 3 A level passes, all at grade A.”
