James Corden celebrated David Letterman‘s last “Late Show” by pissing off Sting outside the Ed Sullivan Theater on Wednesday.

The “Late Late Show” host sat next to the rock icon as he performed “Every Breath You Take,” and then ruined the hypnotic 1983 Police single by improvising some rap verses.

“What are you doing?” Sting deadpans in the segment that opened the “Late Late Show.”

“I just thought I’d add some lyrics to make it a bit more ghetto,” Corden responds.

“We don’t need a big more ghetto. This is a great song,” Sting shoots back. “It’s a tribute to Dave, it’s his last night, we don’t need none of that. Thank you.”
