NKOTB and BSB: Together At Last! Boy band fans were treated to a double dose of nostalgia at New York City’s Radio City Music Hall on Saturday night when ’80s hitmakers New Kids on the Block brought out ’90s-era pop tarts the Backstreet Boys for a duet.

The New Kids thrilled fans as they began to cover the Backstreet Boys’ 1999 hit “I Want It That Way” for the sold-out crowd. The audience proceeded to go wild when The Boys themselves stepped onto the stage to finish the song with NKOTB.
