Three different songs titled "The Power of Love" were in the UK charts at the same time. When, and who were the artists?

You need a "Guinness Book of Hit Singles".
Jennifer Rush, Frankie Goes to Hollywood and Huey Lewis and the News are the three artists.
As somebody else will probably have already typed this, I will add that "Crazy" is a much commoner song title.

Oh and FGTH's version fell out of the UK Top 40 in February 1985 while the other two entered the chart in September 1985, so they were never all in the chart at the same time.
