Rod Stewart has practically made a second career by re-recording music standards. Along with his three albums covering standards, and another covering Motown, he has now “hit for the cycle” with a Christmas album called, “Merry Christmas, Baby.” Yes, there are all the usual covers of carols and hymns, but the twist is with whom he sings duets. There are songs with Michael Buble, Cee Lo Green, Ella Fitzgerald and Mary J. Blige. And to top it off, the album is produced and arranged by David Foster. It’s a well-produced, splendidly-performed album, and Rod has been on every TV talk show to present the CD. He’s got it down to an art, and it works.
