This would be the last song by John Denver to go all the way to the top of the pop charts. “I’m Sorry” was on at #1 on the Billboard chart for the week of Sept. 21 – 27. It was at #1 on the Cash Box chart for the week of Oct. 5 – 11. The song s an apology for forsaken love.

On the “B” side of the single was Calypso” which was a tribute to Jacques-Yves Cousteau and his research ship, the “Calypso.” It also got extensive air play at that time. I think it is a better song but you can decide as I have pasted in both videos. Notice that the “Calypso” video uses some footage from Mr. Cousteau.
