Rock and Roll versus Rock in Roll

Is there anybody out there that Rock’n’Roll actually means Rock in Roll? I accidentally typed it that way in an IM the other day.

Google’s index for the different spellings of rock’n’roll:

–40,000: “rock-n-roll“

–25,700,000 “rock-n-roll”“

–46,100,000 “rock-n-roll“

So 1 in 1,160 have it “rock in roll”

Here are the 10 livejournal users who spell it “rock in roll” (hence the image used above–it’s from one of those profiles.) I tried looking up “rock in roll” on myspace and friendster, but they don’t allow you to search for exact phrases.
