Phil Spector produced the album. Bobby Whitlock, who played keyboards at the sessions, had this to say about him:
"The real show in that whole place was Phil Spector - what a funny guy. He's not too funny now, but then, what he was doing in there and the way he was carrying on, I thought, they've got all these mics out here catching us jamming, where they need a mic is on the inside. He was a pretty colorful character to say the least. That was one of the highlights of it - listening to him and watching him and watching how he operated. I learned a lot just from being around him. He's just eccentric, he's real creative. I agree with his work ethic. I concur with him 100% when it comes to being creative in the studio - put 6 guitars on it if you need it. If it wasn't for Phil Spector, forget about The Righteous Brothers. There probably wouldn't be a lot of us here from 'You've Lost That Lovin' Feelin'
' - you know how many babies were made to that?"
