A Very Barry Christmas is back and just as wonderful as ever! What an icon! A national treasure! We loved every second of Barry Manilow's holiday show at the Westgate Las Vegas! He will be playing many more shows there in 2026! His regular residency is a must-see as well! This cover of Mariah Carey's festive classic was a new addition to the seasonal concert! Such a treat! Watch above! Enjoy! SHARE! The post Mariah Carey Gets The Barry Manilow Treatment! Covers "All I Want For Christmas Is You" - Live In Las Vegas (2025)! appeared first on Perez Hilton.
