It's The Collaboration You Didn't Know You Needed..

Waterford legend Gilbert O'Sullivan has teamed up with Gary Barlow for a performance of Gilbert's 1972 hit, 'Alone Again (Naturally)'.

The former Take That Singer posted the video on his Instagram with the caption 'Alone Again (Naturally) ft. Gilbert O'Sullivan. What an honour to have @gilbertosull_ on #TheCroonerSessions today ! Love this song… Thanks for coming on, and sharing this wonderful music with us ! x'

Gilbert also posted the video on his feed saying 'Alone Again (Naturally). Thank-you @officialgarybarlow for having me on #thecroonersessions. Really enjoyed singing with you, and this is the first time I've dueted on 'Alone Again (Naturally)' which made it even more special.'

Speaking recently on ITV's This Morning, Gilbert says he spends his days in lockdown writing songs. He also said his upcoming album is finished and will be released in 2022.

Now we wait and see if Gary Barlow will feature on it..

Here's the fab duet between the two icons.

Enjoy!
