Gavin-Gwen duet

GET YOUR "GLYCERINE" ON: The killer Gavin Rossdale-Gwen Stefani duet on Bush's smash "Glycerine," performed live with the band, has now been made available on iTunes via Rossdale's label, Zuma Rock Records. You'll find it here. And maybe it's just us, but we'd swear the physical beauty of the singing spouses is so powerful you can actually hear it in the recording. (12/19p)
