ALL THE WAY HOME is a marvelous film! Would love to see that again as well! FYI -- I tried to go to the link listed below to purchase DARK AT THE TOP OF THE STAIRS and got a prompt that the numbered title was not available -- but thanks anyway -- will continue my search and share whatever I find.
In the meantime, TCM -- PLEASE run this film again! As well as ALL THE WAY HOME, if you have it! And a Robert Preston Day is also a fantastic idea!
Speaking of Preston -- I found a youtube of him singing "CHICKEN FAT" written by Meredith Wilson specifically for President Kennedy's Council on Physical Fitness in 1961-- if you were in elementary school during the early 60s, chances are you will remember doing squat thrusts to this record! "Go you chicken fat, go!!!!!"
