"We didn't give a s--t about being popular," the guitar legend recalls of his Cream days

Ginger Baker and Eric Clapton shared two bands together, Cream and Blind Faith, thanks to "being guided by the same star."

"We didn't know how to verbalize it," Clapton says in an unreleased interview clip from the Baker documentary "Beware of Mr. Baker," recalling Cream's shared passion for playing and irritation with fame-seekers.

"We didn't give a shit about being popular," the guitar legend adds. "We didn't have time for it."

Instead, he was drawn to Baker's similar aspirations -- which, nevertheless, led to success for the seminal rock act.

"We were compelled by what we felt musically," Clapton says. "I wanted to play every day in a way that would move me. And I wanted to be with musicians that had that kind of motivation."

"Beware of Mr. Baker," which examines the drummer's musical discoveries in Nigeria and post-'60s life, is out now. The film won the Documentary Grand Jury Prize at the 2012 SXSW film festival.
