Songs from my mother's 8-track

I put this playlist together because my mother had these songs on her 8-track (songs I haven't heard in about 30 years) and after searching for so long, I finally found most of them. Some things have been recently coinciding which helped me find them. I knew how to find some of the songs, but some were very hard (like the song by Odyssey). There is one that I still don't know about and I'm still looking for it. I think that it's an orchestra from the 70's...This takes me back!!!
