The “It’s Always Sunny in Philadelphia” actor spent several days in Boston promoting Four Walls Whiskey.

It’s no Paddy’s Pub, but for 20 minutes on Saturday night, the patrons of The 88 Club piano bar in Back Bay cheered on the whiskey-pouring and piano-playing skills of actor Charlie Day, famously from longtime FX show It’s Always Sunny in Philadelphia.
Day spent the weekend in Boston promoting Four Walls Whiskey, the whiskey brand owned by him and other fellow Always Sunny actors Rob Mac and Glenn Howerton.
The Rhode Island native bar-hopped from Thursday to Saturday, pouring shots of the Irish whiskey and American rye blended liquor to patrons, and even pitched at Fenway Park. Day also gave a wide-ranging interview to Boston.com about his New England upbringing, which included growing up near Rhody beaches and attending Merrimack College.
But at his last stop, he provided a little bit of fan-service to a piano bar full of disciples of the Philadelphia-based sitcom, now in its 17th season. Day’s character in Always Sunny, Charlie Kelly, is musically-inclined, with some of the show’s most famous episodes showing Kelly play piano, harmonica, and even staging a rock opera.
“Ah, man, keyboards just make sense to me, man. I get ‘em, you know?” Day’s character says in the show, implying that the illiterate Kelly never actually learned how to play the keyboard.

So Day, standing just feet away from an open piano, made his way to the stage and played some hits any Always Sunny fan would know — and these patrons, some wearing green Paddy’s Pub shirts, did indeed.
It started with “I like Paddy’s Pub,” followed by the classic “Go F–k Yourselves,” and ended on possibly one of Kelly’s most beloved musical contributions, “Dayman.”
