Today’s Holiday Tunes: Duets edition with Mariah, Buble, Barbra, Gaga, Olivia and yes, Bob Hope!

Found some lovely duets for you and it is no wonder Michael Buble is featured in two of them.

He’s replaced the great Bing Crosby as the go-to CD on Christmas Eve for my family because he is just so perfect at holiday tunes.

Buble teams with Mariah and Barbra here and I also present to you a throwback of Olivia Newton-John and Bob Hope and the unexpected but lovely pairing of Lady Gaga and Joseph Gordon-Levitt.
