It's only bloody Gandalf, hamming it up beside George Ezra in the video for Listen To The Man, the fourth single from his chart-topping album Wanted On Voyage.
The set-up is reminiscent of "Waiting For Godot", as Ian McKellen plonks down beside our deep-voiced troubador on a stage, empty except for a bus stop, a park bench and a backdrop. But this isn't an existential experiment in the theatre of nothing - it's more like Morecambe & Wise in one of their musical stand-offs.
"He [Ian] just keeps butting in and pissing me off," Ezra told the Mirror earlier this month. "And stealing the camera. In real life, I hate being on camera but in the video, that frustrates me.
"It was nerve-racking trying to act beside him. I’m not an actor, and he’s phenomenal."
Even if this wasn't a good song (which it is) this would be worth four minutes of your day. But imagine how much better it would have been if Nicki Minaj had turned up too...
