Chas,
Great post! Sorry to hear about the loss of your friends.
Always loved this tune, I discovered it by accident about 30 years ago when I picked up a piano solo book of Benny Golson tunes. I was actually looking for a sheet to “Five Spot After Dark,”. “ I Remember Clifford” was also published in the same book. I started playing it and I immediately liked the tune and found it within my ability to play. I had forgotten about the tune but took out the book after reading your post and realized with a couple of hours practice I should get the tune back under my fingers.
One added note at my wedding 24 years ago when the band took a break I played a couple of piano solos on my friend’s Kurzweil piano for our guests. One of the tunes was “I Remember Clifford, “. I lied a bit and said the name of the tune was “I Remember Michael” and played it in honor of my late father who had passed quite a few years before the wedding. My father was a very mellow guy and this tune seemed to fit. By the way no one came to me and said “you fraud”

we know the real name of the song is “ I Remember Clifford.”
Thanks again for the memory.
