[citation needed] Brockman began his career as a comedian in vaudeville and musicals in the early 1900s.
Oldman's marketing of the song led to Leo Feist acquiring it and encouraging Al Jolson to perform on stage.
[1] In 1919, he was a co-writer of the song "I'm Forever Blowing Bubbles", which years later would become the anthem of the English football club West Ham United.
He also co-wrote, with Abe Olman, the song "Down Among The Sheltering Palms", published in 1914 and popularized by the Boswell Sisters in the early 1930s.
He died in Santa Monica, California in May 1967, aged 80, and was inducted into the Songwriters Hall of Fame in 1970.
