Uncle GC had to accompany a mixed choir this morn and was greeted with a pianoforte with 3 screws on the lip/edge of the bookrest!!! Had them promptly removed.
Was told some old gent had put them there - for what reason nobody knows, but it made page turning a nightmare.
Here are the piccys... So sorry about the date stamp from the cellphone that was used... can't remember how to turn it off... what with ill-fitting dentures and all...

Unscrewing-ly,
GC
