I saw him on the Grammy's and was sad to remember what a great talent he was. I always liked his music.
Elvis Presley, Frank Sinatra, Nat King Cole, the Mamas and the Papas, Dean Martin, Jan & Dean, the Righteous Brothers and Ray Charles to name only a few.
In 1965 he had significant studio work with Phil Specter as well as with the Beach Boys so much so that he toured with them. Campbell estimated he was earning about $100,000 per year for his studio work in the mid-1960s.
He played on the First Editions psych-drenched ‘What Condition My Condition Was In’ and the 12 string intro to The Beach Boys classic ‘Dance Dance Dance’, and he is playing on Sinatra's ‘Strangers In The Night’
