I had not played with an organized group in almost 25 years and had not played more than a few notes in 20 years. I pulled my flute out of the closet and put it together. The Cork on the head joint was loose but it still worked and I could play a scale from memory. Remembering how to play it was like riding a bicycle, no problem. However remembering how to read music proved to be a bit more challenging, I pulled out my fingering chart and went to rehearsal a couple days later.
