The song This Must Be Love is performed by Denison Marrs .
you say 'till the end as you hold me close
the music starts and the dance begins as we sway turn and bend
promises are made and the words you say seem to heal and mend
i say to myself this must be love
everytime we meet you become a bigger part of me
and everytime we leave it tears a hole through the heart of me
so go ahead take me in
break me down and then build me back up again
and we'll stay 'till the end or forever
whichever comes first until we ascend.
