the backwards song box - mary-kate & ashley olsen lyrics

ashley, what is that gizmo?
it’s a backwards song box.
you take a song.
feed it in this tube.
turn this dial.
press command b flat.
and out it comes, backwards!
try some of our alb-m.
‘double up, double up, two are in the middle, double up, double up’
‘pu elbuod, pu elbuod elddim eht ni era owt, pu elbuod, pu elbuod’
oooo i like that.
