Still searching for this Walter Murphy album and/or track!

I have searched every conceivable place on the WWW looking for this Walter Murphy trak "Your Planet Or Mine". It was the b-side to the 1982 45 records of his Dance to the main theme from E.T. It also appeared on an MCA special projects label titled "Best Of The Movies". I figured if anyone would either have this or know where to obtain an digital copy of this album and/or track, it would be here. I have seen many auction sites selliing the 45 RPM; however I haven’t had a records player in many, many years.

ANY help would be greatly appreciated,

Thanks,

Daryl from Maryland
