- He has a brother? - Exactly.

- I hear you, but Collab has been doing

a really fun thing where they each try out for every song,

and it's been really energizing for them.

[in German accent] To please der label?

[both chuckle]

[vocalizing]

[cheers and applause]

- Two terrific performances. Now for the judging.

For stand-up comedian Mario Cantone,

four stars!

And for singer Lesley Wiggens...
