Song(s) suggestions to sing at a bar?

Me and 2 friends are planning to practice and sing a song at one of the bars we go to. Preferably an older song back in the days, and not newer songs.

Stuff he wanted to do:

Sweet Adeline

[b]Hello my baby[/b] (Full version, of course.)

What I wanted to sing:

Can't take my eyes off you

Any suggestions? And serious ones, please. Ones that fits the criteria. I don't want to sing songs from Justin Timberlake or whatever.
