Thank you. I at first thought USA where there are over 50 towns or cities named Newport. I appreciate the clarification. That would then be the Newport mentioned in the poem by Idris Davis, later set to music by Seeger?
There's also several in the UK.
Newport Pembrokeshire
Newport Isle of Wight
Newport Shropshire
Newport Essex
Newport Gloucestershire
Newport Monmouth/Gwent (this is the one they mean!)
And yes, Newport Mon. is the one meant in "Bells of Rhymney"

Cheers
Nigel
