Peyton Manning Joins Chris Stapleton on Stage to Sing 'Tennessee Whiskey'

Former Indianapolis Colts and Denver Broncos quarterback Peyton Manning is apparently staying busy in retirement. 

As explained by TMZ Sports, Manning recently joined country music performer Chris Stapleton on stage at the Red Rocks Amphitheatre near Denver. The 41-year-old and Stapleton sang a duet of "Tennessee Whiskey," one of the star singer's hits. 

Some out there may remember Manning hasn't been shy about showcasing his pipes in public forums in the past. 

Turns out Manning's voice is good for more than those catchy Nationwide jingles.
