I found this website that contains several Nights related children's records from the States in the 1950s and 1960s, they are great recordings and you can visit the site and download them yourself. If I ever figure out how to host them in an embedded player here I'll post them. There's all the usual stories plus one has the Physician Douban!
here's the website: http://www.artsreformation.com/records/
And some pictures of covers (these would make great t-shirts):
