Vin Diesel, typically a hardened, stoic action hero on screen, has lately made a habit of showing his softer side off-screen, by uploading a surprisingly moving rendition of Rihanna’s “Stay” or a hilariously awkward dance to Beyoncé’s “Drunk In Love.” Now, out promoting Guardians of the Galaxy, he has mustered all the sensitivity he has to cover Sam Smith’s “Stay With Me,” currently No. 3 on the Billboard Hot 100.

Diesel’s lower register is actually not half bad, although his falsetto is another story. Still, Diesel’s shortcomings didn’t stop Smith himself from offering kudos.
