Having used many rolls of gaffer's tape, I can assure you while the
old
duct tape and gaffer's tape may share the same fabric structure, the
adhesive is very different. Gaffer's tape adhesive is made to have a
relatively strong hold, but to not leave any residue when removed.

If you mess up the stage floor the dancers will kill you with their
bare feet.

Gaffer = grandfather, it means the master electrician. His assistant
is the Best Boy, once the senior apprentice.
