BILLBOARD – While some struggle to find the perfect wedding gift for long-time pals, Shawn Mendes gave his friends something they will always remember: a performance of an original song he had composed for the newlyweds.

Mendes wrote the song, titled “Try My Best,” based on a love letter the groom penned for the bride. The singer-songwriter, responsible for such heartfelt smashes as “Stitches” and “Treat You Better,” sang while strumming an acoustic guitar, as the couple enjoyed what appeared to be their first dance as man and wife.
