Bublé sang and then kicked his leg out before belting out more of the song while twisting his leg back and forth. “I’m sitting on a rainbow” – When Michael Bublé stepped onto The Voice stage on May 19, he didn’t just sing — he brought back the golden age of swing with effortless charm and a wink to the past. Performing “I’ve Got the World on a String” during Season 27’s Live Finale, Bublé lit up the room with big-band energy, Sinatra flair, and that smooth, velvet tone that has made him a modern-day crooner icon. But this wasn’t just a performance

When Michael Bublé took the stage during the first night of The Voice Season 27’s Live Finale, he made sure to pay tribute to two music legends he’s long admired.

During the live May 19 episode of The Voice, Bublé and his band performed Frank Sinatra’s upbeat, swing classic, “I’ve Got the World on a String.” Wearing a dapper black suit with a sparkly floral pin on his lapel, the reigning champ of The Voice added a little choreography in between the lyrics. Choreography that looked a lot like Elvis Presley’s iconic stage kicks and leg swivels.
