Jimmy Rowles March 18th & 20th, 1960
Lordisco says the sessions happened precisely on the 18th and 20th, Bruyninckx lists the sessions as occurring BETWEEN the 18th and 20th.
Also, tracklistings with composers' names and run times are impossible to find online. There are a couple hard copies of the LP for sale on Ebay, but they do not show the rear cover where that information might be found. Allmusic, amazon, itunes and other sites which usually have SOMETHING do not in fact list the tracks. It is clear, however, that this session's tracks were from two musicals of the time: Fiorello! and Little Mary Sunshine. While this doesn't help much in terms of running times, at least we can glean the composers of the songs.
