Judy Stone was often on the charts in Australia from the early 60s to the mid-70s. Most of her singles were versions of current or recent releases from America or Britain (with a couple of exceptions from Sweden and Italy). Her pleasant voice and personality boosted the appeal of the local product, and occasionally she would co-chart with the original version.

Single on Epic, released November 1963. Arranged by Ray Stevens, produced by Bob Morgan.
Kerri Downs, born Mary Lou Kiernan, released five singles 1963-66 on three labels. She was married to singer-songwriter-producer Gerry Granahan, and joined girl group The Angels for a while, recruited by Gerry (though she had left by the time of My Boyfriend's Back). Gerry's wide-ranging career included recording as lead singer of Dickie Doo And The Don'ts and co-writing their first hit Click-Clack (1958).
Co-writer Artie Wayne also wrote Marcia Hines's From The Inside and co-wrote Ray Brown's Go To Him. Joey Powers' 1963 hit Midnight Mary is also an Artie Wayne-Ben Raleigh composition. Ben Raleigh's credits include Dinah Lee's Do The Blue Beat, written with Pretty Flamingo composer Mark Barkan, another frequent collaborator.
