I am looking for a song that probably came out somewhere in the early to mid-seventies. The chorus goes something like this:

"I don't want to say I love you
I saw a sign that said 'dead end;'
I just want to hold you close to me
When loneliness comes again.

I don't want to say I love you
I don't think I can take that pain;
You were the northern lights on a July night,
And I was a southbound train."

Anyone?
