"Groovin'"

I listened to a couple Elvis Presley albums yester-day because it was his birthday, and I found a similarity between his "My Baby Left Me" (written by Arthur Crudup) and Manfred Mann's "Groovin'" (which the Groovin' with Manfred Mann EP credits to King and Bathea, apparently Ben E. King and James Bathea.)

To me, it sounds like the third verse of "My Baby Left Me" starts with the lines:

Baby, one of these mornin's, Lord, it won't be long

You'll look for me, baby, and daddy will not know

although some internet sources I referenced transcribe the lyrics (with odd line breaks) as

Baby, one of the mornings

Lord, it won't be long

You'll look for me

Baby, and daddy, he'll be gone

In any case, the second verse of "Groovin'" starts with nearly identical lines:

One of these mornin's and it won't be long

You'll look for me, and I'll be gone

Because the lines resemble each other so closely, I think this is an intentional similarity, but I'm not certain.
