I posted the original lyrics to "Thanks for the Memory" (note: Memory, not Memories) in the thread called Songs from old movies. The lyrics at the web site mentioned above are not the original ones. After Hope adopted the song as his theme song, he changed "Memory" to "Memories" and rewrote the lyrics (or his hired writers did) to suit himself and the times. I think he sang many versions over the years.

To appreciate the original, you have to see in the context of the film. If I remember correctly, Bob Hope and Shirley Ross play a divorced couple who encounter each other by accident after a long separation. They chat awhile, and discover that, although they don't regret getting divorced, they still have some affection for each other. They sing the song to each other as a duet, alternating verses. I found it well-acted and rather touching, the highlight of an otherwise frivolous film.
