I love golden oldies songs such as "you are my everything", "unchained melody" etc...
I like to play the songs with my guitar and can someone tell me which website got lots of guitar chords for golden oldies.
well, you could use the google to get any guitar tabs or chords that you want. If you want to go to specific site then there are some good ones like ultimateguitar.com, guitartricks.com.
IF you are a beginner and want to learn songs fast and easy then you gotta use guitar pro software and get the associated files from mysongbook.com(which i think is temporarily fighting some copyright battle) and ultimateguitar.com. This is one hell of a software if you want to learn the songs, any song.
