Michael Bublé was amazed when he asked fan Richy Brown to sing at his show on the spot, and Brown nailed it, singing a beautiful version of “Fly Me to the Moon.” Bublé was shocked by Brown’s voice and said it sounded like a mix of Mariah Carey and Frank Sinatra.

Budweiser singer Michael Bublé liked how Brown didn’t just sing the song like Frank Sinatra did, but added some jazzy scat singing at the end to show off his own signature style. The video below has been seen 4.6 million times.

Before the show, Bublé made it clear that he had never heard Brown sing before. This meant that the singer had to take a big risk with the bit, just like he did at his huge event at the Ziggo Dome in Amsterdam. Brown did a great job and sang like a pro. Bublé praised her for having the guts to sing without practicing in front of such a huge crowd.

This kind of unplanned contact with fans is something that Bublé loves to do and often does at his concerts. At another show, the Canadian traditional pop star asked a fan who is 17 years old to sing “I’ve Got You Under My Skin.” You can see this below. Of course, the teen also knocks it out of the park when singing the song, which was made famous by Frank Sinatra.

American composer Bart Howard wrote “Fly Me to the Moon” in 1954, and Kaye Ballard recorded it for the first time later that year. Following that, many artists recorded the song, which eventually became a jazz standard. The most enduring version is no doubt Sinatra’s recording, which was included on his 1964 album It Might as Well Be Swing, which also featured pianist Count Basie and his orchestra.
