From Spencer Gibb's wiki:
... the first child of Robin Gibb, an English musician and member of the Bee Gees, and Molly Hullis, who worked as the personal assistant to the Beatles' manager Brian Epstein until his unexpected death in 1967. Gibb's godfather was Robert Stigwood,
He unknowingly made out with Madonna on the dance floor of a New York City club.
