I heard this "mommy mommy do" song in the radio and couldn't find anything about it.

Random info:
- I heard it in the radio in Brazil. So it must be some famous song.
- It's old. I guess from 70s or older
- It's a long song
- sometimes I think the guy singed in German, or English with accent
- In the final section of the song this "mommy mommy do" repeats lots of times. Some other voices join the main voice in this final section. Reminds me of ABBA in the chorus style but I don't think it's them.
- As this "mommy mommy do" repeats a lot, it would be easy to find the lyrics but I couldn't. So, maybe it's not "mommy" but something similar, like "honey" or "mama".
- I'm also not sure of the "do" after the "mommy". It's how it sounded to me, as I'm not an English speaker.

I was driving and couldn't record any samples. But I was sure I could find it later.
Unfortunately I'm unable to name a genre or style for the song, because I can only remember this last section.
