I'm looking for a musician. I have a CD of his, but it's been
scratched. I can only get the first 3 songs to work. I know the
artists' name, but that hasn't helped me in my search. His name is
Chris McNulty (McNolty?), and I know he recorded the album in
Philadelphia. The music is pop, akin to Gordon Lightfoot, I'd say. The
chorus in the first song is "You better chin up, put your glass down,
and get your spirits up". The second song is "Baby I've been crying
like a baby over you", and the third song's chorus is "you've been
looking at the moon all night, counting the stars in the sky". Any
help would be much appreciated.

I haven't identified the songs you referred to, but the female jazz
singer Chris McNulty sings "Philadephia" (by Neil Young) on the album
"Brightness of Being". Could it be this artist? Probably not, as you
made it clear that it's a guy.
   
"Brightness of Being features an impressive cast of performers,
including saxophonist Gary Thomas, drummer Terri Lynn Carrington and
singer Chris McNulty.

Add in a three-part classical opus, a lovely rendition of Neil Young's
Philadelphia featuring vocals by Chris McNulty"
