Tuning a concert piano with humidity control

[Phil Ryan]

On the same subject, I was tuning the concert piano on stage for the 
concert that night and just as I finished the last section,  someone 
flipped on the stage spotlights and immediately the piano lost 2 cents 
in pitch across the board.  I figured it would gain back those 2 cents 
when the lights went out etc.   Does everyone tune concert pianos with 
the stage lights on?
