Overwatch - We Are Number One by Edwyn Tiong

Reaper, Sombra and Widowmaker sing "We Are Number One" from Lazytown. Because why not?

Based on "We Are Number One" produced by Máni Svavarsson for the television series "Lazytown"! Given how big Lazytown memes are right now, I hardly think I'd need to tell you that this song is based on this super catchy earworm:

The song was rendered with the aid of the original stems graciously provided by Mani Svavarsson, the composer of the song! He released the stems as part of a special live Facebook event celebrating the song "We Are Number One" becoming the meme sensation it has over the course of the last few weeks/months:

In a strangely sweet twist, the reason for Lazytown's sudden memetastic status was to raise awareness of Stefan Karl Stefansson, the actor for Robbie Rotten on Lazytown, and his battle with cancer. Many of the Lazytown memes link to his GoFundMe page to help with his treatment and I will also post that link here:
