I never could understand the lyrics in the chorus, and before the days of the internet I had no idea what they were actually singing...Turns out, I was singing along the same "words" that they were! Ba de ya! Who knew?!
I just love that song. It's so joyful to sing and dance to:
♪ Ba de ya, say do you remember
Ba de ya, dancing in September
Ba de ya, never was a cloudy day ♪
