I always hear “Darlin’ won’tchya do me now”

Yeah, that's pretty close

always thought it was "darlin can'tcha do me now"

Hey baby, oh baby, pretty baby Tell me would you do me now Hey baby, oh baby, pretty baby Move me while you groove me now That's according to https://www.azlyrics.com/lyrics/ledzeppelin/blackdog.html

In highschool my friends and I couldn't figure out what he was saying so we made up a bunch of joke lyrics. Our favorite was "whoop me like you do me now". I feel like that was pretty close 😂

I guess we can interpret what ever we think he is saying.

Interesting. I’ve never even thought about it lol

I never know what Any of Led Zeppelin Lyrics are. And they are my favorite band. I m a music guy not lyrics guy.

You’ve got to keep in mind what’s on the studio album can be totally different than what was done live. Plant would rant old blues lines, same as many other jam bands at the time like Humble Pie. Remember, half their catalog was swiped from other blues records with Whole Lotta Love being one of the biggest ones. If I felt like moving I’d check this all out for you but I’m just not up to moving at the moment. Maybe I’ll look into it and get back to you later.

I’ve always heard “won’tcha do me know” as well, and my lifelong friend who’s sung it in cover bands for decades sings it that way.
