Do Balrogs have swings?

[narfforc]

As Gandalf was a-thrusting,
and he was a-swinging
with his trusty Glamdring,
Balrog was a-dodging,
and the bridge it was a-cracking,
Balrog was a-falling,
note he was not flying,
although he was a-trying,
and he was a-failing,
for to be a-floating,
or to be a-gliding,
he needs to grow that wing thing.
