There is no link with the Billekens family.
De Electronica's (Bert van Gageldonk, Jules Ketelaars and Marijn Heeren) was originally a Dutch sociable orchestra that mainly performed in a pub called De Kroon in St. Willebrord (The Netherlands).
Between 1967 and 1983 they released sixteen singles.
In 1980 they reached the eighth place in the Dutch Top 40 with De Vogeltjesdans (Chicken Dance).
The trio also brought The Billekes dans and De Poesjesdans as a single out.
