Had a clarinet, and my first 'formal' music training on it, from 1961 to 1964. Havn't blown anything since about 1968, when I tried an alto sax for a short time.
However I was given my first guitar in 1959, a Rosetti single cutaway Jazz box, with a single pickup screwed to the neck. Shortly after got given Bert Weedons' 'Play in a Day' first edition ! :)
