What is the name of the original song wich I know by the name “flute-barcode brothers”?
Is there an original, its name and artist and anything but remix… thanks

Best answer:

The original song featuring the tin whistle (or penny whistle) is an old folk Danish song, but the rest is purely Barcode Brothers, and the song is originally theirs.
