So there he was … Charles Barkley MURDERING a karaoke rendition of “End of the Road” at a bar in North Carolina when suddenly …

the guys from Boyz II Men appeared on stage and saved his ass.

It all went down at a bar in Raleigh — Charles and B2M were in town for the Jimmy V Celebrity Golf Classic to raise money for cancer research.

After Charles hit the links, he grabbed the mic during a karaoke event … and proved once and for all that his voice is EVEN WORSE than his golf swing.
