These guys covered 'Baby on Board' from The Simpsons on a rooftop

We might've found the perfect homage to one of the most memorable songs on The Simpsons.

You might remember "Baby on Board," the catchy-as-hell song written by Homer Simpson for his barbershop quartet The Be-Sharps in the classic 1993 episode.

As the end of the episode, Barney, Principal Skinner and Apu reunite on top of Moe's Tavern in a comeback concert, a nod to the Beatles' final public performance in 1969.

To jog your memory, here's the moment from The Simpsons.

Wel,l an Irish all-male chamber choir by the name of The Ramparts performed a cover on top of the Green 19 café in Dublin, complete with an enthusiastic crowd looking on, as per a video uploaded on its Facebook page.

Okay, it's more on a balcony, but hey they sure sound good.

It's certainly a performance worthy of getting out the tear gas.
