Lid Prop on Performance Pianos

[Joel Rappaport]

Here's another question for the List Members:  One of the things I like
to check when on standby for a concert is that the lid prop is placed in
the correct position when the lid is opened.  I was wondering if anyone
has had a bad experience of the lid being shaken loose if the prop is in
the wrong hole in the lid.  Some artists get pretty enthusiastic when
playing and, if the lid prop is not correctly positioned, has it been
known to slip?  Maybe I am worrying for nothing??
