There's the track "∞" (infinity) on the album 666 by Greek rock group Aphrodite's Child - actress Irene Papas chants "I was, I am, I am to come" repeatedly and wildly over a percussive backing.
According to wikipdia,
"The track was considered lewd by record company executives, and resulted in the album being withheld from release for two years by Polydor Records. Upon its release in 1972, the song caused some furor in Greece and was again accused of lewdness and indecency by Greek religious figures and government authorities."
