song Title and Artist Question

Trying to find out who sings a song and the song name…

The only part I know is some of the song Goes… Singing this silly little love song… I thought it was either Paul McCartny or the Beatles but I cant find it anywhere on the net

Well, there’s a song by Paul McCartney called “Silly Love Songs.”

I checked that one but it didnt match what I remembered hearing

“Just an old-fashioned love song, playin’ on the radio…”? Paul Williams?

Could it have been this?

I checked the Jude one too even found a sample of it online somewhere
