Yes, it depends on who you ask. I had never heard the original song until this year. I was born in 75 and have never been line dancing at the YMCA! A point to you for even knowing Amos Moses!
Well, I still listen to some country stations, and Jerry Reed’s version is still getting the occasional replay, so it’s not like it’s going to die any time soon. Heck, they still play Elvis Presley songs occasionally, and he was far more rockabilly than country, so yeah, they’ll keep playing Jerry Reed’s stuff, too.
For what it’s worth, I’ve never been line-dancing at the YMCA, either. Heck, I’ve never been line-dancing at all, and I promise you, everyone else’s feet are happy about that. If you’d ever seen me try to dance, you’d understand what I mean.
