Mamberg was born in Haifa, Israel, but his family moved to the United States when he was a child.
[1] He later moved to England, and in 1972 joined forces with his friend Alan Merrill, at the time well-known in Japan, to found the band Streak (in which Mamberg appeared and was credited as 'Jake Falsworth'), a band which later evolved into the Arrows (in which he appeared as 'Jake Hooker').[2].
[3] Merrill wrote the song "I Love Rock 'n' Roll" for the Arrows, giving a co-writer credit to Hooker by way of settling a debt.
[9][10] He retired as a musician in 1978 when the Arrows disbanded, moving to Los Angeles to manage Luft.
Their marriage ended in divorce, following which he continued to reside in Los Angeles, working as a publisher, producer, manager, and entrepreneur, until his death.
