Christmas has certainly come early for Beach boy and Hanson fans.
Isaac, Taylor, and Zac from Hanson have collaborated with the Mike Love and Bruce Johnson from the Beach Boys to perform "Finally It's Christmas" live on the "Today" show.
The first concert the Hanson brother ever attended was one by the Beach Boys, so this pairing was a dream come true for Hanson.
Hanson even talks about the influence the Beach boys had on their music.
Watch the full performance above.
