Promotional release for Telfort, a Dutch telecom company, while BT acquired the company, hence the BT logo which was used at the time.
Telfort are now defunct.

There are grooves on each side of the disc but no music, just silence. As a result Jimi Hendrix and Bob Dylan are credited on the sleeve and disc but are not featured.

The disc labels both sides as Side 1.

The text on both sides of the disc state: -
Beschikt u niet over apparatuur om deze single af te spelen.

This translates as: -
