At long last, ‘Bangity Bang” has been heard! On the second episode of “How I Met Your Mother” last night producers finally unveiled the song that’s been sung (and went viral on YouTube) made up by the cast as a gag. The show’s noted composer John Swihart wrote a whole, serious sort of tongue in cheek R&B ballad around what had been just a joke chorus that was previously sung by cast members.

The HIMYM producers wanted a real soul singer to record the song. So he reached out to R&B legend and Rock and Roll Hall of Famer Sam Moore, whose hits include “Soul Man” and “Hold On I’m Coming.”

Ironically Moore, who’s 77 and often noted as Bruce Springsteen’s favorite singer, recorded the song in a Phoenix, Arizona studio–the same place where last night’s episode took place. Sources say Swihart played guitar, bass and piano on the track. The word is we’ll be hearing Moore’s “Bangity Bang” more during this final season of “Mother.” Maybe he’ll even sing it at Ted and the newly revealed Mother’s wedding at some point!
