Who sang the song Rainbow, you got me down on my knees, rainbow. A rock song in the early 80's?

Was it Clapton or did he just do a cover version, I was a young(ish) kid when it was out but remeber the beat well. I want to find the song again.

Layla by Eric Clapton?

It's "Layla, got me on my knees, Layla..." Not Rainbow!

Actually, an artist named Rainbow wrote it.

The Marmalade (Brit group late 60's 70's) sung it originally.
Not aware Clapton done a cover version.

There's Clapton's 'Layla', as Derek and the Dominoes.

Layla, you've got me on my knees.
Layla, I'm begging, darling please.
Layla, darling won't you ease my worried mind.

Do you mean Layla? Yeah that was Clapton.

Its Layla Eric Clapton
