yoodling in middle of song

[dcp1970]

I'm desperatly in search of a song that came out in the 70's. I don't know the artist or the title. The only thing I can remember is in the middle of the song the singer does this sort of yoodling thing accompanied by an organ, and then it procedes to go into some heaver rock. I know it's not much to go on but that's all I have. Any help is appreciated thanks.

Woman or man singer and was the song heavy sounding all the time?

No doubt the song youre talking about is "Hocus Pocus" by the Dutch rock band Focus.
Weird song, but lotsa fun also.
