The Voice’s Adam Levine, John Legend, Kelsea Ballerini and Michael Bublé teamed up for their first-ever performance as a quartet to help promote the upcoming 27th season of the singing competition.

The song choice for the occasion was Elton John’s 1971 hit “Tiny Dancer.

Adam, who previously spent 16 seasons coaching artists on The Voice, has three wins to his credit: Javier Colon in Season 1, Tessanne Chin in Season 5; and Jordan Smith in Season 9. He is the third-winningest coach behind Blake Shelton with 9 wins and Kelly Clarkson with four wins.

This will be the 10th season for John, who took off last season, and who to date, only has one win with Maelyn Jarmon.

This marks Michael’s second season as a coach, and he previously served as a Season 3 advisor to Blake Shelton. He won his first season with 31-year-old Sofronio Vasquez from Mindanao, Philippines.

Kelsea Ballerini is a first-time coach, but she isn’t a complete stranger to working with artists on The Voice. She served as Season 16 battle advisor for Kelly Clarkson, and she filled in as coach during Season 20 when Kelly was ill.
