10 years after their big win on "The Sing Off", Pentatonix is at the top of their game and on top of the world! 4 of the 5 members of this iconic a cappella music group join me today for a delightful chat. What about? Oh, how the group was formed, some of the obstacles they've overcome, the importance of leaning on and learning from each other, and just what make them, "The Lucky Ones." (And if you're looking for some advice on how to write that elusive second verse, you won't want to miss what they have to say!) Join us! ~ Delilah
