Frank,
I took one group lesson from you. Tune you taught that day was Pete's 'Singing In The Country' or 'Living In The Country' --- Key of D I think. It was the first time I'd ever tried to play and pick further up the neck than the first 3 frets.
Then you left to Join the Weavers and I never took another formal lesson again---but I sure did learn from folks I ran into all over. One time at the Gate Paul Clayton guested at one of those Sunday afternoon hoots that went on for several years.

Do you remember that strange section at the Gate--it was sort of a peanut gallery -- set aside for teens who couldn't drink yet.-- Just Coke was served there.------Wow, almost forgot that.

that reminds me of a night at the bar at the original Second City--on Clark Street right near Wisconsin St.   I was under-aged but loved to hang out there and just listen to the talk. Very cool. Nelson Algren hung out there too. He was piqued because I only ordered Coke. Once Mr. Algren shoved his own beer down the bar to me--to the consternation of the bartender.---------- My MS sure screws up my recent memory, but the olden golden times seem to be with me still. --- All the best to you and Mary! I do hope you both are well. ----- Art
