Vince McMahonVince McMahon’s grown children, Shane and Stephanie, were embarrassed yesterday when a group of houseguests overheard the WWE chairman belting out the song “Stand Back” in the shower.

“When I was just a boy, everybody told me, what I should do, and who I should beeee!” McMahon crooned at the top of his lungs while lathering himself.

“I never will be just an ordinary guy. I’ll always push harder reaching for the skyyyy!”

Shane and Stephanie gently encouraged their guests to relocate their brunch to the poolside of the McMahon mansion in Stamford, but the guests appeared to be enjoying the unexpected serenade.

The elder McMahon, who performed the song Stand Back on the 1987’s Piledriver: The Wrestling Album 2 — and danced awkwardly in a schmaltzy, Tom Jones-inspired video for the song (below) — has always been proud of the song, and typically espouses the cockiness conveyed in its lyrics.

His wife, Linda, quietly excused herself from the brunch table, tiptoed upstairs and tried to encourage McMahon to quiet down, but the bathroom door was locked and McMahon was singing too loud to hear her.

Mortified, she listened as her husband crescendoed to a roaring climax: “I’m a man running wild, heading for the top, never slowing down, never gonna stop, and along the way you’ll see a lot of men drop. Baby watch ’em drop. Baby, baby, baby, watch ’em drop. Stand back!!!”
