The Toronto Maple Leafs forward, while playing for Hockey Club Davos back in November, joined MySports One TV in Switzerland for a lengthy interview that included a brief musical interlude.
Thornton joined host Reto Müller for a drive and chat in what appears to be Switzerland's version of James Corden's "Carpool Karaoke."
Thornton sings
The singing starts around the 14:30 mark of the video. Thornton and Müller belt out Britney Spears' 1999 pop mega-hit "Baby... One More Time."
"Oh, Britney, sure!" Thornton exclaims. "Let it roll! Who doesn't know this song?"
Spears climbed the charts during Thornton's second season in the NHL. Thornton is about to start his 23rd season, which Müller pointed out during the interview.
For the encore performance, Thornton and Müller performed "I Was Made For Loving You," by KISS. Thornton said he's seen in concert a few different times, including once during his younger days in Boston where "we painted all up, me and some of the boys."
The interview also covered Thornton's fondness for skiing and taking an outdoor dip in freezing temperatures. The show also featured a video clip from San Jose Sharks forward and former teammate Timo Meier.
