Later in 1970 Hot Chocolate, with the help of record producer Mickie Most, began releasing tracks that became hits, such as "Love Is Life", "Emma", "You Could Have Been a Lady" (a US and Canadian hit for April Wine), and "I Believe in Love". All those releases were on the Rak record label, owned by Most. Brown and bassist Tony Wilson wrote most of their original material, and also provided hits for Herman's Hermits, "Bet Yer Life I Do", Julie Felix, "Heaven is Here", and Mary Hopkin, "Think About Your Children".
