For Wilson Phillips, recording their new holiday album, 'Christmas in Harmony,' wasn't entirely harmonious given some of the circumstances behind it. This past June, the group was working on the album with producer Glen Ballard in a Hollywood building that had no air conditioning.

"It was so hot, it was sweltering," Carnie Wilson tells PopEater. "We were actually sweating during this Christmas recording. The air [conditioner] was broken. But there was a vibe in there and [Glen] was like, 'Well Annie Lennox just finished her last record in this booth.' We said, 'We don't care if it's broken. We want to record there.'"
