Maman. As mentioned there, he recorded his song in French, Spanish and Italian. So this single presents the Spanish version, and even the B-side 'Les beaux dimanches' appears here in that language.
It's not inconceivable that I would never have bought either single if Jean-Jacques hadn't participated in the Eurovision Song Contest, because it's such a sentimental song. But there you go.
