Lady Antebellum's son steals the show with unexpected appearance on stage

Lady Antebellum singer Charles Kelley gave fans a show-stopping act before they even got started on their Manchester tour stop in the U.K.

Charles' wife Cassie uploaded the Instagram post last year when her son took the stage with his father in what would become the most adorable mic check ever.

In the clip which can be found below, Charles walks onto the stage quite matter-of-factly holding baby Ward in one arm. When he reaches the mic, it's off.

You can hear him sing random notes before requesting the mic be turned on. When it is, he repeats the notes and then leans his son forward to the mic.

That's when Ward steals the show as he energetically repeats the notes in his own baby style. They do this again and Ward obliges with even more excitement.

Charles then sings a part of the kid show "Bob The Builder" before singing part of the classic "Twinkle Twinkle" song.

Each time, his son gives his own version, stealing hearts in the crowd. But soon enough, as most kids do, he tires of the whole thing and is ready to move on.

Young Ward seems to already be part of the band. He certainly has the singing part down.

His father said in an interview with PEOPLE that his son had "seen more in two and a half year than [he] ever saw in [his] 24 years of existence until this band."

Of course, Ward doesn't realize that he's going so many places, but Charles says he's a "sponge," taking in everything and hopefully enjoying the variety of lifestyles as in an Amsterdam trip where he was "enamored" by the many bikes.

His dad certainly appreciates traveling now. He said: "I love Georgia, but there's just so much beauty in the world."

One of these beauties was the miracle that the couple were able to have their son after the fertility issues they went through. "... it really did feel like kind of a miracle," Charles said. "And I don't want to miss a thing."

Charles explained that he doesn't want Ward to say later on in his life that he never saw his dad due to traveling, so he likes that Ward and Cassie can move around with him.

He further described his son's current phase being a "monkey see, monkey do" one where he copies whatever Dad does. It's no surprise then that Ward was so quick to sing into the mic.

Someone else who copied Lady Antebellum's music was Adele back in 2010 at the CMT Awards.

The British singer paired with Darius Rucker to perform their rendition of the band's famous hit, "Need You Now."

Adele's well-known powerhouse voice brought out the emotion along with Rucker's husky vocals.

It touched the audience and Lady Antebellum's singer Hillary Scott, moving the latter to tears.
