Who sings "Its a lovely day" from that Benadryl Allergy commercial?The song is in the commercial that has a guy with a kleenex sneezing as the background and scenery changes, and then they show the Benedryl, which is where he clears up and runs off to play with a kid or something. Help! LOL!

I haven't seen the commercial, but Bill Withers sings a song called "Lovely Day," maybe that's it?

Supposedly Little Jack Melody and His Young Turks is the band, but according to his official website, he had no idea about it.
