In 1985, Wise-Z Records released an LP containing a cover of Ed McCurdy's Last Night I Had the Strangest Dream, with Silent Night as the B-side. The performances were attributed to the Spacelings: a trio of cartoon aliens named Zara, Zig and Zog.
Accompanying the record was an animated music video made by Moon + Parrot Productions, a small company founded by Simon Holden and Keith Graham. The studio became the Holden Film Company in 1986.
As far as I can tell, there were no further Spacelings projects, although it appears that they may have been intended to become a franchise in the manner of Alvin and the Chipmunks.
