Continuing our trek, we get to 1969 - and two very different, yet strangely similar songs.
In the UK, an Antipodean swimmer, artist and television personality revives a Civil War song and has the Christmas number one with it. In a recent program, he discovered the reason his family didn't like him singing it - it reminded them of his relatives who died in World War One. Here he sings it in a version that is being released for the Christmas number one this year.
Meanwhile, in the US, a trio of folk singers have their last number one hit with a John Denver song. Again, this is taken from a recent live show.
