Need Help So close 60's maybe 70's

OK this one has really got me stumped.. The only lyric I know in the song is, "You are in my life forever"... It almost sounds like boston/kansas.. they sing in like 3 part harmony on the part I put in quotes.. It could be "you where in my life" forever.. .I have googled them words several times and cannot find anything close.. including youtube... If you can help me I would be so grateful.. It very well could be kansas/boston.. Im pretty sure it has a piano in it as well..

Try "I Cant' Let Go" by Air Supply

Nope this wasn't it.. They sound a little bit more manly.. I heard it on pandora once and never got around to checking who it was.. goodness I hope i find this song so I can blare it going down the highway..

Makes me think of ....1976

England Dan & John Ford Coley - "Nights Are Forever Without You"
