Anyone know who sang the French DBZ theme in the Basque and Galician dubs?

I was comparing the Spanish, Valencian and Catalan themes, to the Basque and Galician themes. Even though Catalonia, Basque Country, Galicia and Valencia had the same French "OAVs/Movies 1 - 9" instrumental, except that Spain made their own instrumental, I wondered who sang it. I know Txell Sust sang the Spain version, while Jordi Vila sang the Catalan version, and Coral Cubells sang the Valencian version, but who sang the Basque and Galician versions, since the dubbing studios didn't credit them? There isn't any proof on any wiki platform due to unconfirmations, nor had any interest about it.

Here's the two versions of the same theme:
