Short story long: I have an old car and a "tape reader" (don't know the name in english) and I'm listening to old tapes.
The song I am looking for contains french and english (mostly french).
The english parts are short and mostly repeated twice lyrics.
There is this song which has the following lyrics (sorry if there are only bits of them, I never manage to get it in my head):
Sans effort, je vous amène aux métaphores
comme les papillons qui se mêlent et s'entremêlent à la belle saison
illuminé d'azur dans les yeux s'évapore
Sur un air de disco disco (no mistake here, it's said twice)
Chabada chabada chabada, ho chabada chabada
I have tried shazam (written search, did not have it when in the car), google and youtube without success.
