Naturally, they received a heroes' homecoming when they returned to Dublin on August 6. A massive crowd filled Dublin's Dame Street for their first public appearance back home and, as you do, they decided that a song befitting of the occasion was "All I Want for Christmas is You" by Mariah Carey.

Carey has a strong connection to Ireland. Both of her maternal grandparents immigrated to the US from County Cork, and she's previously said of her mother, Patricia Hickey, "She's so Irish, she loves Ireland, she's like, yay, Ireland! Waving the flag and singing When Irish Eyes Are Smiling. And that's great. I appreciate that and respect it."
