Unexpected Song (From "Song & Dance")

I have never felt like this For once I'm lost for words Your smile has really thrown me This is not like me at all I never thought I'd know The kind of love you've shown me Now, no matter where I am No matter what I do I see your face appearing Like an unexpected song An unexpected song That only we are hearing I don't know what's going on Can't work it out at all What ever made you choose me I just can't believe my eyes You look at me as though You couldn't bare to lose me Now, no matter where I am No matter what I do I see your face appearing Like an unexpected song An unexpected song That only we are hearing
