Tom Fletcher of U.K. pop rock band McFly has been a dad for over a year, and since his son, Buzz, was born in March 2014, Fletcher has taken to Instagram and YouTube to post adorable pictures and videos of the two of them together.

Although McFly isn't as well-known in the United States, Fletcher became an online sensation when he posted his 15-minute wedding speech, which was actually a song of thanks to his wedding party, online. The video has about 16 million views.

After Buzz was born, Fletcher soon shared the viral spotlight with his son when he posted a two-minute-long video of his son laughing uncontrollably at dandelions.

On Sunday, the McFly singer posted another short video of the duo on Instagram singing to The Commodores' "Easy." It's clear that Fletcher is already getting Buzz ready to take the stage soon.
