Last night (March 13), the fun continued for Justin Timberlake, who is in the midst of a week-long stint on Late Night with Jimmy Fallon to promote The 20/20 Experience. Following the previous barbershop version of "SexyBack," Timberlake and Fallon pulled off another funny performance. Of course, JT also played a song from the new album.

This time, they teamed up with soft rocker Michael McDonald to sing "Row, Row, Row Your Boat." They all dressed up as McDonald, wearing white wigs and fake goatee beards and adopting an awkwardly breathy singing style.

As for the song from The 20/20 Experience, Timberlake led a large ensemble (which included the Roots) in a six-minute rendition of "Let the Groove Get In." Many of Timberlake's backing musicians played hand-held noisemakers and percussion instruments, while others sang backup and played horns and the singer showed off his dance moves.

Watch both songs below.

The 20/20 Experience is due out March 19 via RCA Records.
