The Capaldi episode premieres March 24th. You can expect more like it if this initial foray proves successful, Hyams said.

A cover song show represents a familiar and frequently successful strategy (see BBC Radio 1's Live Lounge as an example). It gets artists out of their comfort zones and, in many cases, sheds light on the stars themselves. However, that might be just what YouTube needs. The site is (mostly) shifting away from scripted originals, and it needs a tentpole series or two to reel people in.
