What is this look I often see faces filled with ecstasy what's going 'round,tell me what have they found I've been searchin' for the answer trying to work my feelings out I been up all night,girl nothing is goin' right Since we met I've had some problems with words I couldn't say now you've changed my life forever Chorus: This must be love the one I heard about no other kind of feeling turns me inside out Yes this must be love controlling my heart and mind let's take a vow to make it last 'til the end of time,'til the end of time. It's a strange sensation,a new creation and I just don't have a defense against it I'm completely outdone for the first time there's only one the things I did,I don't do no more there's no desire,no looking for who or what is to blame no it cannot be explained since we've met I've had some problems with words I couldn't say now you've changed my life forever -Repeat Chorus- Bridge: Something's come over me you're all my eyes can see whatever it may be
