Annette Funicello

The Mickey Mouse Club was hosted by Jimmie Dodd, a songwriter and the Head Mouseketeer, who provided leadership both on and off screen. In addition to his other contributions, he often provided short segments encouraging young viewers to make the right moral choices.
The opening theme, "The Mickey Mouse March," was written by the show's primary adult host, Jimmie Dodd. It was also reprised at the end of each episode, with the slower it's-time-to-say-goodbye verse.

"Puppy Love" is a popular song written by Paul Anka in 1960 for Annette Funicello, whom he was dating at the time and wrote it in her parents’ living room, no less. The song reached #2 on the Billboard Hot 100 and #33 on the UK Singles Chart.

Annette was one of "many Teen Sweethearts" in the 50's.
