For those curious...
The Benny Hill theme song actually originated from an older song called Yakety Sax done in the 60's. whatever file share program you have, type in "Yakety Sax" and for the artist type in "Boots Randolph." There is a guitar rendition of this as well, appropriately called "Yakety Axe" by Chet Atkins(RIP). Although Benny Hill adds some different music into it, the base of the song is found within these two songs.
Hope this helps,
