I counted 14 or 15 sessions Lucky did during his first stay in Paris, recorded between February 22 and May 11, 1956, issued on 9 different LP's or EP's, all of them issued under his name! More than pretty much any other American in Europe did in such a short time!
His second stay yielded 12 more sessions between June 1957 and Spring 1961, not counting those in other European countries (another 3 or 4), but this time only 4 were released under his name.
There was another stay between 1968 and 1970 with LPs in Germany and Spain and live recordings from Switzerland.
B-3er, Lucky quit playing music because of his frustration with the business side of music. For a while he lived in a cabin in the woods, even on the streets of Seattle; last report I found was he was in an insititution in the Seattle area with no more remembrance he once was a great jazz musician. But it's hard to find definite details. There were some (probably deleted) posts on the BNBB about this.
