A few things from 70s memorabilia lists:
1. That Canadian guy doing a spoken word tribute to America or Americans. I can't remember any details except that it played on AM radio all the time and everyone listened to it all the way through every time it played and nodded their heads with solemnity and a sort of understated pride. I think there was some patriotic music in the background as he said shit like "Americans understand the value of freedom" in a booming voice (although I can't accurately remember one single line). Everyone talked about how wonderful it was and how only a Canadian could do it and that if an American had done it, it wouldn't have counted.
He was probably getting a hand job from Nixon while he was doing the recording.
2. That one song that was a nun (I'm pretty sure it was a nun) singing "Our Father who art in Heaven ..." No other details. Maybe it was called The Lord's Prayer? It played constantly as well. Unlike the Canadian guy America tribute, everyone sang along to God Song and talked about how singing the Lord's prayer along to a radio was a modern permutation of religion.
3. Clarence Carter's 1971 song Patches.
4. Paul Anka's Having My Baby.
5. Charlene's 1977 hit I've Never Been to Me. Don't remember it? Here's a tickler from your humble hostess:
