Too many years have passed since Mr. I. entertained me and my peers. I do remember anxiously awaiting, but not anticipating, the theme of the next show. It was always a surprise to see the inventiveness of the writers although the only thing clear in my memory is the miniature train, with Mister Tripp as the engineer, disappearing into whatever scenery was deemed appropriate for the evening's telecast. Through the years of adolescence and on into adulthood the show's theme song, lyric and melody, have perpetually haunted my memory
Now, I may be wrong, but if memory serves I believe the lyric to the song went as follows:
I wish I were I wish I were I wish I were just tell me, I promise you it will come true whatever you wish you wish you were.
Someone in the cast would say, "I wish I were Abraham Lincoln", or "I wish I were George Washington", and then Paul Tripp and company would segue into whatever theme was appropriate for that particular show. Very entertaining for a nine year old with a vivid imagination.
