Jun Hyun Moo presented an unforgettable performance at the '2019 Idol Star Athletics Championship.'

On February 5, day 1 of the annual event aired on MBC. Jun Hyun Moo, who is also the main MC, turned into Freddie Moo-cury for a special celebration stage. 

With his signature white tank and mustache, Moo-cury made idols laugh with his hilarious performance of "We Will Rock You" and "We Are the Champions." And despite his poor singing, Moo-cury carried on the performance with much seriousness. 

Watch his amazing stage in the clip below.
