Sting, Shaggy & James Corden Sing 'Subway CarPool Karaoke' at 2018 Grammy Awards

James Corden took his signature Carpool Karaoke bit underground on Sunday night (Jan. 28) at the 2018 Grammy Awards, bringing Sting and his new musical mate Shaggy along for a subterranean ride during the broadcast. The bit, renamed "Subway Car(Pool) Karaoke," found the unlikely trio busking on a Big Apple subway car with just an acoustic guitar and a boombox for unsuspecting commuters.
