Wow, hard to say. 3 Dog Night song came out in 1970, and I heard it a lot. MaW song came out in 1980 and later it was everywhere.
1970 3DN release 2 albums. One Naturally which had Joy to the World on it and It Ain’t Easy, with Mamma Told Me Not to Come.
Down under is a song I heard and listened to. Didn’t buy the album, wasn’t a fan. 1970, I was 7 years old and music was making an impression on me and it was around that time I received my very first record player with 2 stereo speakers and I was the music king of the world. Both MTMNTC and JttW got a lot of rotation.
On the other hand MaW never got played on my home stereo in the 80’s. Catchy tune and it never got turned off once it started to play on the radio.
I like 3DN more.
