I have plenty which I'll dig out of my old VHS box and if the tapes haven't shed too badly I'll digitise them and upload. I know I have Kai Kai Kakaruk and Luki Loto adds.
Actually it's a Tok Pisin version of the Nine Network Australia promo which aired at the same time in 1987. I believe Nine was an investor in EMTV at the time. Nine Network Australia was an ABC USA affiliate and hence this is where the promo originated. ABC USA used this song in 1978-79. There is also a version in english for EMTV and Motu. I have a copy of all of them. Will post later. These are all off my own VHS recordings whilst living on Lae PNG at the time.
