This Bruno Mars friendship song, from his debut album Doo-Wops & Hooligans, has a great message and an upbeat feel. This well-crafted arrangement features accessible choral writing with fun harmonic grooves and stylized backing vocals. Chord symbols are included for an optional simple ukulele or guitar part, or the piece can be done with piano, and the SATB voicing can even be sung a cappella. Highly recommended!
