The story is great! For those still reading rather than ROTFL, the main thing is to use piano dollies, easily rented at most rental places. On stairs, use planks if at possible. Tie things very firmly on trialers or trucks, pad well, including under the ropes where they cross the piano. Use ratcheting straps if you don't know much about knots, like most folks. If you do, use a taut line hitch so you can untie it without a knife when you get where you're going. It WILL move some and work your knots some, no matter how well you tie it down. With a grand or baby grand, take the legs off and tie it on its side against the wall of a box truck or trailer. Don't carry it on it's feet since the legs will break unless the road is glass smooth and all turns are taken dead slow. The legs are designed to bear the downward load only.
Based on experience with a large freezer chained and locked shut chasing a guy down the stairs and pinning him rather brutally against the wall, I don't think you want someone on the down side. Use burlap "tump" lines or something from above so no gets killed if the thing gets loose.
The guy below the freezer was black and blue from neck to ankles for about a week. We found out from the lady AFTER the incident that the freezer was filled with her husband's rifle collection. /forums/images/graemlins/tongue.gif
