The boys hit the Big Apple last week and gave fans a taste of the album by performing the disc’s first single, “Thinking ‘Bout Something” on “Late Show With David Letterman.” The song also shipped to music download stores Friday while the tune’s video, featuring “Weird Al” Yankovic and reminiscent of the pawnshop / music store scene in the 1980 movie “The Blues Brothers,” gathered millions of views online.

Shout It Out lands in stores June 8.
