What is the song "J'ai Garde L'accent " by French singer Mireille Mathieu about?

I've tried Google Translation but the English translation does not make sense. Is she talking about keeping her Avignon accent, or what? I've just discovered her on You Tube and I just love all her brand of music, even though they were mostly recorded during the 60's and 70's.|||Each region has its accent. Mireille has done many concerts in different places. She kept her Avignon accent. This accent is her identity, she wants to keep it:) C'est l'accent de... Mireille !|||She's talking about all the beauty of the region she grew up in near Marseilles and says that she kept her accent because she loves where she is from.
