Yes, they still do... I've been there three times in recent years, and I've found and talked with people of all kinds and ages... Usually there's whiskey around, so the last time I brought some! It was raining the last time, and all the people were still there, enjoying the rain, talking about Jim and toasting, and singing "...my only friend, the end..."

Chopin's small and discreet place is always full of tons of colorful flowers and sweet and delicate fans.

Everybody was shocked or smiling... I think even the video crew were laughing at him... Amazing!
