"Too Late For Goodbyes"/"Norwegian Wood Disco" connection?

Listening to Disc Two of Don't Call Me Ska Face: The History of Ska, I noticed a bit of possible Beatlejamming -- on the track "Norwegian Wood Disco," a Ska Boys cover of the Beatles song (not quite "disco," and owing as much to dub as to ska due to all the echo and delay and tape-manipulation), the skankin' guitar riff that plays throughout is EXACTLY THE SAME as Julian Lennon's "Too Late For Goodbyes." Since I can't find any information on the song online (and the CD didn't come with a booklet), I have no way of knowing which came first. Anyone know? I'd like to think the "disco" in the title places it in the late '70s, but I could be wrong.
