Will Smith brought back the Fresh Prince and rapped 'Summertime' on 'The Late Show'

The Fresh Prince is back.

Well, at least for one performance. 

On "The Late Show with Stephen Colbert," Will Smith brought back his Fresh Prince rapper persona and performed his and DJ Jazzy Jeff's hit "Summertime" for the audience during a commercial break - but now you can watch it, thanks to the glory of the internet.

"The Late Show" house band Stay Human began playing the tune while Smith and Colbert were chatting, then Smith couldn't resist breaking out into the song.

In a season when there really isn't a Song of the Summer, it's great to revel in a classic. This is how it's done, folks.

Watch the full performance:
