I'm not sure, but there may be something that you can help me with as you're a RTTY operator. About thirty years ago I picked up a teleprinter printout that had a song on it sung to the tune of 'The Battle Hymn of the Republic' and it went something like this:
Mine eyes have seen the glory of the teletype machine
It is printing out the message typed upon the keys of green
In a far and distant hamshack where I have never been
go marching on
The chorus was a repeated RY RY Hallelujah and it went on for three or four verses. Have you ever seen this piece?
