To say the least, the Beatles were unique, not only for their music, but also for a few band member Brain Types. Paul McCartney,the leader of the pack, is a #11 FCAL, a rare design when it comes to male singing stardom. In fact, there hasn’t been another well-known #11 male singer for as long as BTI can remember (they have been more plentiful on the female side, including Faith Hill, Paula Abdul, and Olivia Newton-John). The other unique Brain Type band member was John Lennon, a #14 BCIR, McCartney’s near opposite design! That’s a sure way to explore most possibilities. Not only are both Brain Types uncommon in the general populace (especially the #14!), but to have them singing and playing together in the same boy band is quite something!
The below interview is old, recorded in the early 90s, but the insight is every bit as relevant. A younger Bob Costas (#15 FCIL) interviews a younger McCartney, asking him about the late Lennon. Notice, first, how Paul corrects Bob in his grammar as to which of them (McCartney or Lennon) was the oldest. “Older,” says McCartney, “not oldest.” Leave it to the language loving #11 to know his proper English! At any rate, embarrassed Bob quotes McCartney as saying John Lennon was “the smartest” and “the quickest wit.” McCartney agrees, and goes on to say, “John was not very forthcoming about what he felt. He was quite a private person.”
