The story:

It took me 7 years to figure out the lyrics ... My
friend and I were talking about old songs we used to
listen to, and this one came up . Deciding to listen
to it, for old time's sake, we looked it up on
Youtube . We were watching a video with lyrics on it
. When it came to this part, I was astonished ! I
couldn't believe I had sung it wrong all that time
