It must take you ages to do all of that colour coding !!
The following was lifted from the www., it basically explains things and saves me typing it out !!
I suggest you also read the sleeve notes from Mirwood Vol 1 on Kent. Mr Croasdell also tells the story ...
say hi to Sue
" Sherlie Matthews dated and fell in love with Frank Wilson, a fellow singer and potential record producer, whom she had known for years. The wrote songs together, and Frank recorded one of their efforts "Long Long Road to Happiness" on the local label Power Records under the pseudonym of Sonny Daye.
They performed together as an act, and Sherlie made her first record when Power Records released a single by "Sheri Matthews and Sonny Daye" titled "Come Back to Me".
Frank got a break by joining Motown as a writer and producer and he subsequently introduced Sherlie around and she was signed up as a singer/songwriter/producer.
She was to forge an extremely successful Motown career - with record production and songwriting for The Jackson Five, Martha & the Vandellas, Diana Ross. Marvin Gaye, The Four Tops and The Supremes.
Sherlie joined the Mirwood label, and became a real powerhouse behind the scenes of this household name label. "Bob and Earl" were responsible for 12 of the 36 single releases - either jointly, separately, or under pseudonyms. But Sherlie was also responsible for a huge chunk of the labels output in 1966 and 1967, both from her own group The Belles, and through writing for and producing Bob and Earl, Jackie Lee, The Mirettes, The Olympics and Bobby Garrett."
