Once the band began playing “Home,” Shelton came onto the stage to join Bublé and Foster. He wore a shirt and blazer for the appearance. Shelton’s country contribution and Bublé’s jazzier delivery established the contrast at the center of the performance, with both singers conveying the song’s emotion while making their parts appear effortless.

Peter Cetera also participated in the concert, performing a medley. The soft rock singer had collaborated extensively with Foster as a songwriter; their shared credits included “You’re the Inspiration,” recorded by Cetera’s former band, Chicago. Their continuing friendship was apparent during the show as they exchanged smiles from across the stage and expressed appreciation for each other’s work.

Cetera’s medley formed another part of the evening, but the Bublé and Shelton performance became the segment that attracted particular attention online. One viewer suggested that the duet alone explained why repeat buttons were created. Bublé was singled out for the smooth quality of his singing as he moved through the melodies of the song he co-wrote, while the “Home” collaboration remained the concert performance that most captured the Internet’s interest.
