Hanson Sings National Anthem in Three Part Harmony! (Video)

Hanson takes the field to sing “The Star-Spangled Banner” at the Tulsa Drillers minor league baseball game against the Arkansas Travelers at ONEOK Field on Saturday (May 14) in Tulsa, OK.

The brothers – Taylor, Zac, and Isaac – are Tulsa natives and performed a beautiful three-part harmony rendition of the National Anthem.

“Singing the National Anthem tonight at the @TulsaDrillers game! Hope to see you all here! -ITZ,” they tweeted earlier in the day.
