It's been driving me nuts for years

I have pieces of a song, popular in the late 70's (I think) and not knowing the name of the song, or the artist, is making me crazy!

Lyrics included in the song (sung by a male voice, very much in the same vein as Thin Lizzy's "Wild One" and possibly around that time too, include:

"She's taken the Black Rose [could be "Back Roads"],
- That's all I ever heard her say....
- Don't take "no" for an answer....
- Or she's gonna, slip away....

(Chorus)
Black Rose! [could be "Back Roads"], Black Rose! [could be "Back Roads"],
She's slip-ping away....!!"
(etc)....

PALEEZE HELP!!!!

try more than a feeling by Boston.

I know they have some lyrics like

I looked out this morning and the sun was gone
Turned on some music to start my day
I lost myself in a familiar song
I closed my eyes and I slipped away


Try that

actually it may be this verse by Chicago --

Hard to Say I Sorry

"Everybody needs a little time away," I heard her say, "from each other."
"Even lover's need a holiday far away from each other."
Hold me now. It's hard for me to say I'm sorry. I just want you to stay.
After all that we've been through, I will make it up to you. I promise to.
And after all that's been said and done, you're just the part of me I can't let go.

This is the whole song -- try this out!

"Everybody needs a little time away," I heard her say, "from each other."
"Even lover's need a holiday far away from each other."
Hold me now. It's hard for me to say I'm sorry. I just want you to stay.
After all that we've been through, I will make it up to you. I promise to.
And after all that's been said and done, you're just the part of me I can't let go.

Couldn't stand to be kept away just for the day from your body.
Wouldn't wanna be swept away, far away from the one that I love.
Hold me now. It's hard for me to say I'm sorry. I just want you to know.
Hold me now. I really want to tell you I'm sorry. I could never let you go.
After all that we've been through, I will make it up to you. I promise to.
And after all that's been said and done, you're just the part of me I can't let go.

After all that we've been through, I will make it up to you. I promise to.
You're gonna be the lucky one.
