sn\\\\song from 1950's with Wendy in the lyric

I was named after a song from the 1950's (probably 1957 or 1958) that I believe was about a girl named Wendy who's boyfriend (husband?) is going in the navy and he is asking her if she will wait for him....BUT, I'm not positive about the lyric.

I do not know the name of the song or the performer, but I do it is not Bring Back Wendy by the Elegants and it is not any song that is newer than 1958.

I'm looking for the lyrics, performer and possibly where I can get a copy (even a '45 would be great).Can anybody help me out?

Try Bobby Vinton or Bobby Goldsboro

Is it "Don't Be A Hero"
