In the last few minutes I have just stumbled upon a very interesting video archive on Youtube. It is mainly featuring the late Ian Paisley but you can see what seems to be the late John McKeague in the background on the right hand side. The video is dated 1969 and McKeague can be seen at the very start and on a few other occasions.
Wonder if William McGrath was there too?
