Attention OLDIES experts: Need info on song....?

Ok, my dad is wanting a copy of the lyrics to a song. He says the title is 'If'. Just 'If'. He thought it was by Little Anthony and the Imperials but I have been to there website where they list 15 of their albums there and all the songs on each album. That song is not on any of their albums.

If I Google "If lyrics", I get almost 60 Million hits. I have surfed thru several lyrics sites to no avail. I went to Time-Life's website and read thru all the 50's and 60's CD collections they have to see if the it was on one them but I found nothing.

I just don't know how to narrow down the search for the lyrics when I have no idea what the song sounds like or who did it. I just spent over an hour surfing the net and I had my hubby (who is an awesome searcher) surfing for about an hour this morning.

Dad says it would have come out late 50's, early 60's and was done by a motown group (it sounded motown/blues). My dad is looking for the lyrics not a copy of the song.

Thanks!!
