A punter at Michael Bublé's recent show had the unthinkable happen when Bublé
himself handed her his microphone.
When Bublé asked the crowd about the songs they love to sing in the shower, Erin’s hand shot up. She said Etta James' "At Last" was her go-to song, and her sister Allison tried to coax Bublé into passing over his microphone.
"Ask her to sing it!" she shouted.
When Bublé actually did, no one in the crowd was prepared for the voice Erin showed off.
When Bublé took his microphone back, he called Erin the next 'American Idol' and threw compliments at her voice.
He also made it clear that the surprising moment straight out of A Star is Born was not set up in advance.
