Nice montage!
Sky started of with Omnitrax, as we can hear. In 1994 when they wanted a sequel JAM couldn't provide it because no American station ordered a sequel. So for the first time a station from the European continent went to JAM to do a brand new custom package: SkyTrax.
The demo JAM put out was sung for WLTE Lite FM 103. Since then Sky had an annual follow up, sung bilangualy (station name and slogans in English, frequencies in Dutch).
I think it's one of the oldest logo melodies still in use (1989-2007) in Europe…
