Neil Young sings SLOWPOKE on his concert video "Silver & Gold" but it's not on the album by the same name, or any Neil Young album that I can find.

However, I found these lyrics at AZLyrics.com:

SLOWPOKE
Neil Young

Something opened up the gates again.
I can't control it, so I rushed right in.
Here comes a mermaid and a little girl,
Saw open drawers from around the world.

I got some medals hanging on my chest.
I've seen some good ones, but I missed the rest.
Lady Luck, don't you turn on me.
I'm just a student of your history.
I'm just a student of your history.

Slowpoke, I'm gonna run with you,
Wear all your clothes, and do what you do.
Slowpoke, we got some things to find.
When I was faster, I was always behind.
When I was faster, I was always behind.

Something pushed back the curtain again.
The stage is empty and the crowd is thin.
The song is gentle, but the song is now.
Something's missing, but something is found.
Something's missing, but something is found.
Something's missing, but something is found.

Slowpoke, I'm gonna run with you,
Wear all your clothes, and do what you do.
Slowpoke, we got some things to find.
When I was faster, I was always behind.
When I was faster,
When I was faster, I was always behind.
When I was faster,....
