Children performing at 'Garden of Dreams' Talent Show at Radio City Music Hall

NEW YORK (WABC) -- The "Garden of Dreams Foundation" is hosting their annual talent show Monday night.

100 children will get the once in a lifetime chance to play at Radio City Music Hall, and before their big night a big Broadway star offered up her advice.

"I remember performing for the first time and being so scared that not a lot of sound came out, but the second time more came out, and the third," said Renee Elise Goldsberry, "Angelica" in "Hamilton" on Broadway.

Goldsberry was invited to "The Garden of Dreams" talent show rehearsals, and she gave each act feedback.

"I'm such a huge fan of hers! For her to say I was great was just amazing!" said Caroline Watters, Sunrise Day Camp Cancer Survivor.

It was an intimate setting to get tips from someone who has been where they dream of going.

The talent show allows children like Jordan and James who have faced life setbacks from illness to bullying to poverty to see the possibilities beyond their obstacles.

"Garden of Dreams hooked us up with Shawn Mendes and Shawn surprised us," a participant said.

Meeting cool people is something Renee says these guys should get used to, because opportunities like playing a big stage means more special invitations are ahead!

"'Hamilton' has afforded my access to thing like this rooms that I never would have walked into, and so while people are still inviting me to come and meet beautiful young people I'm going to show up!" Goldsberry said.

"April 11th, Radio City, come and see us," a performer said.
