I'm one.
I had seven years of lessons age 8-14, then quit piano to concentrate on a band instrument that was more social and got me more fame (All State Band my senior year, playing for President Johnson at the Astrodome opening, and the school band was invited to the Rose Bowl parade the year after I graduated, pity I missed it).
No music in college, off to the Army and then a career that was very demanding. I bought a piano age 32 and practiced some tougher pieces for a year in a motel until I bought a house and got involved with people around - and I concentrated on work. I did play for a church junior choir for about four years which was not technically demanding (except the guitar pieces) but was quite rewarding socially.
I quit working age 58 due to the dangers and irritations of the job, and playing on piano (and organ, now they cost <$200) is such a cheap hobby. I may be less focused when my income doubles when social security payments start in 18 months, but I have plenty of time on my hands now.
I've had one piano lesson since 1964, and the new lady last year I didn't like the teaching piano (a Yamaha console player), so that was the end of that relationship. Besides her style points were so conventional and mine are so different. Pity though, she knew something about popular arrangements playing by ear that I don't. I've made a lot of progress by myself though, in my pedestrian workman like style. Practice make perfect, if you don't count my style which is unfashionable to put it mildly.
I've had two organ lessons, concentrating mainly on playing posture (very different) and sounds of the pipe organ (so mysterious). The legato style of the organ is no difficulty; much of my piano repretoire doesn't use a sustain pedal.
