Tip Of My Tongue

Hello.

I always used to associate this song with Knock on Wood by Eddie Floyd, because it has a similar vibe (both are great songs). But for the life of me, I just can't remember the title, artist, lyrics... barely anything from this song.

I remember it had a male vocalist, it was in E (for you music theory nerds out there), had a very prominent main riff, and I'm pretty sure it's from the 60s. It's an R&B/soul type thing of the era, but almost like a precursor of modern rock too. That's all I remember.

I would really appreciate it if someone knows it. It's driving me nuts not knowing!
