The Smurfs (1978 commericals for National Benzole)

In 1978, National Benzole (A now defunct British gas company) created a series of animated commercials featuring smurfs to promote the company selling smurfs merchandise. The commercials used the instrumental version of Vader Abraham's "Smurf Song" which came out the previous year to promote the release of "The Smurfs And The Magic Flute" film.

Not that much was known about these commercials until the official BP Youtube channel uploaded one of the commercials on November 8, 2013. However the other commercials made by National Benzole are still missing. The only evidence that other commercials were made was from a 1978 magazine advertising the company partnering with The Smurfs.
