Hello/Bonjour

The date of the piano concert has been changed to 9th October, as the 4th September was too early and a lot of people were still on holiday.
La date du concert de piano a été modifié au 9 octobre, car beaucoup de personnes étaient encore en vacances le 4 septembre.

Please confirm to me if you wish to attend.
Merci me confirmer si vous souhaitez assister.

Happy Holidays! Bonnes vacances!
