This is the longest period of time Sam has ever spent on one leap (2 weeks).
After Sybil in Leaping in Without a Net - November 18, 1958 (1990), Tamlyn Matsuda was the second psychic who could sense Al's presence without being able to see or hear him.
The title is based upon the 1970's song by The Grassroots.
This is the first time where Sam explains both who he is and why he is there. He also explains this in Season 5 with the Evil Leaper episodes.
In the original history, Tamlyn Matsuda was murdered on February 14, 1985 and was the seventh victim of the Chinatown Strangler. Four other women were subsequently murdered.
