Hello there Jim! I loved that song, (and I actually lived at number 7 in those days!) There's a super book called 'All I Ever Wrote' by Ronnie Barker, and Fats Waller Song is listed in the contents. It's published by Sidgwick and Jackson, the ISBN number is 9780283073342. This book is available on ebay, and looking at the contents list on Amazon, there's an enormous amount of material in it (as the title suggests) The song was indeed written by 'Gerald Wiley'. Hope this may be of use. Kind regards, Eliza.
