Which makes perfect sense: if you graduated from high school in 1977, then you and your classmates were born in 1959 (give or take a year). As per the link, Gary was still in the top 20 for baby boy names in 1958 and 1959, sliding a bit to #22 in 1960.
If I ever get a blue cat I will gleefully name him Grover. Grover is my absolute favorite Muppet monster.
And rarely better than here:
I had 2 students named Oscar in the same class last year. I think it’s more popular in Hispanic families.
Maybe you’re not looking in the right place. You can find the poems here:

That is the very bit that made me fall in love with Grover. He is so cute.

Me too! Small world. It definitely was a reference to the muppet, specifically his hair.
It’s a mixed up, muddled up, shook up world.
I’m glad someone got my reference. OK, I’m sure others did too; it’s not like the Kinks’ song is at all obscure.
There’s also singer Elmo Shropshire, of “Grandma Got Run Over by a Reindeer” fame.
Is that with or without a comma? 
I knew an Ebenezer back in the 80s. He’d have been born around 1970.
Retro naming?
