Billy Thorpe (1946-2007): British-born singer, guitarist and songwriter whose family emigrated to Brisbane in the 1950s. Based in Sydney from 1963, 'Thorpy', with The Aztecs, had numerous pop hits in a variety of styles, but at the end of the 60s, then in Melbourne, he fronted a loud, rocky, blues-based formation of the Aztecs that contrasted with his earlier pop idol image. Later, his solo and business career took him to Los Angeles, and he wrote two popular autobiographical books, Most People I Know (Think That I'm Crazy) and Sex And Thugs And Rock'n'Roll [AbeBooks link].

The writer of Sho' Know A Lot About Love is Buddy Mize, a Nashville singer-songwriter who was also one of the backing singers for the Hollywood Argyles, with Paxton on lead vocals and the drummer Sandy Nelson on "garbage cans and… background screams", among other personnel.
One of Buddy Mize's better known credits is for (You Keep Me) Hangin' On, written with Ira Allen, on the 1974 Ann Peebles album I Can't Stand The Rain (not the same song as The Supremes' You Keep Me Hangin' On).
Buddy Mize was a co-founder of the Nashville Songwriters Hall of Fame Foundation. Country singer-songwriter Billy Mize is his brother.

The Blue Jays were originally formed in 1959 in Melbourne, where they recorded on the Crest label. Laurie Allen, later of Bobby & Laurie, was their lead singer in the early 60s. They were joined with Brisbane singer Tony Worsley in 1964 to record on Sunshine as The Fabulous Blue Jays. By that time drummer Bob Johnston was the only remaining original member of the band.
