I was back for one night at the GSO 5 years ago as both principal players were injured.
It was fun to play but the orchestra ended up not honouring my payment because the conductor cut one rehearsal.
The reason he cut it was that we were already playing really well and he was afraid of over-rehearsing burnout.
So the orchestra ended up cutting my pay by about AUD40.
I swore that was the last time I helped them out.
Seriously, I come to the rescue out and you fuss about such a small amount?!
Another fun fact: my old colleague came in for the rehearsal to play the 2nd part and when he saw I was playing he called in sick for the rest of the week so another player had to come in for him.
The good 'ol days....
