Many years ago I attended a concert held by the Signal Hill Alumni choir (I used to go to every one they held every year usually around Christmas time....)
One year, they performed a song that was so beautiful but I couldn't pronounce the words....so I used to make up mih own words.....

Many years later, I was reading Nelson Mandela's autobiography (The Long Walk to Freedom) in which he describes a song that he and the other prisoners used to sing to keep them going while they worked in the lime quarries......I realised it was the same song the Signal Hill Alumni Choir used to sing (and still does) at their concerts.....
This is my musical tribute....."Tchotcholoza" aka The Train Song.....
p.s. I am trying to find a way to upload my audio copy of Signal Hill Alumi's version.....until then enjoy this version.....
