Hello Didier13,
There is already on the site a handwritten score entitled "un dimanche à la guinguette" submitted by Michel on 6/10/2011, but it is Jean-pierre Surimeau.par contre Maurice Larcange has well recorded with Marc pascal on an album also entitled "un dimanche àla guinguette.
I think that it is well this waltz which you seek.
Evi-danse.
