While this podcast is dedicated to Frank Sinatra, the Four Seasons, the Four Lovers, Frankie Valli, Bob Gaudio, Nick Massi, and Jersey Boys are mentioned in the very early part of the interview.
Charlie Calello was a member of the Four Lovers and for a short time officially part of the Four Seasons. He was also the primary arranger for huge percentage of Four Seasons and Frankie Valli songs and albums.
George Clinton, who could be categorized as the Master of Funk, was originally part of the doo op band The Parliaments. During this period, he lived close to both the The Monotones who wrote the song "(Who Wrote) The Book Of Love," and the The Four Seasons - who incidentally released a cover of "Book Of Love" on the Big Girls Don't Cry CD distributed by Rhino Records in 1995.
These doo op memories of George Clinton come compliments of an interviewed on NPR. According to the interview, his band The Monotones, and members of the Four Seasons (probably before they were called Four Seasons) competed against each other in local New Jersey battle of the band contests.
