Here is a quote from the LA Times:

There's a third songwriter listed — Spirit's Jay Ferguson, who composed the tune's bedrock motif in 1967 as a stab at an Afro-Cuban riff.

"I love the record," he says. "Orbit and Beck, I consider them pop subversives, which I really appreciate, and they've made a summer anthem that's very hip and has some darkness and has a lot of fresh sound to it.

"To see what was basically record one in my life, the first thing I ever recorded, come back in such a contemporary fashion is great."

Well it seems as though Jay did get credit after all.

But I still think these people are crap!
