“Can they perform in this building, the anthem in under 90 seconds with a good presence and with good vocal quality?” said Matt Chmura of the Boston Bruins.

The audition was brought about by the retirement of the iconic Rene Rancourt who sang the anthem at Bruins home games for four decades. The team decided it will choose around 25 singers to fill Rancourt’s shoes.

“I am pretty excited. I haven’t done many auditions like this,” said Oladunni Oladipo.

The duet from two sisters was perhaps the most unique.

A panel of judges watched from various spots in the building and will review a recording of the performances over the next couple of weeks.
