As Pat Robson's daughter, I was fascinated to read so many comments about him. He was indeed a unique and remarkable man. I have kept all his letters to and from bandoneon enthusiasts and I watch the Repair Cafe on TV often wishing he was with me to comment on the musical instrument repairs! He was a skilled craftsman, inventor and music lover and I miss him greatly. If anyone would like to have his letters/instructions/information I would be happy to send them, since otherwise I will have to dispose of them and thinking about that makes me sad. Cut-off date is March 1st. Drop me an email and I'll post them to you.
