4 Unknown Songs. Please help identify.

I am almost 100% sure all of these songs are by the same artist. They were recorded on a tape reel mixed with hours of other popular songs from the 70s and 80s. Each link below is a recording of the one of the four songs I posted on youtube. The tape is pretty beat up so the sound isnt perfect. Turn up your volume... Please help me find this album/artist. Thanks!

#4 was posted in another thread. I have #4 in my record collection but can't remember the title/artist - I'm thinking around late 1970s something along the lines of a b-side of Pablo Cruise, Barry Manilow, Little River Band, or Dire Straits. When I come across it I'll post the results.
