LeBron James, Draymond Green Sing At Brent Faiyaz Concert In Toronto

LeBron James took in a concert Thursday night, but it wasn't the Taylor Swift show in L.A. ... instead King James attended Brent Faiyaz's show in Toronto with good friend Draymond Green -- and the hoopers were clearly having a blast!

And for once, LeBron even knew the words! 😅

Concertgoers spotted the NBA champs and agent Rich Paul in what looks to be a VIP area, rockin' back and forth to Faiyaz's "Dead Man Walking" hit.

You can tell LeBron definitely knew the song ... he was singing word for word.

Of course, the NBA legend has been known to flub a line here and there in the past.

Whether it's a track by Lil Baby, Pop Smoke, or 6lack's "Stay Down" (remember "yabadabadodobo old navy" -- the lyrics are actually "Hoppin' out the car, no photos, baby.")

All kidding aside, it's awesome to see LeBron in good spirits, out and about ... after the terrifying health scare his family endured last week, when his son Bronny was hospitalized after going into cardiac arrest.
