This was written by Danny Hamilton and his wife Ann. Ann Hamilton explained: "In the 1970s, as a youngster, I was privileged to have access to the recording industry. At that time, I was married to Dan Hamilton of Hamilton, Joe Frank, and Reynolds. Dan had a huge hit record 'Don't Pull Your Love,' when we met.

By the time we married, Dan, Joe Frank, and Allan Dennison were working on a new album of original songs. As fate would have it, Dan had some difficulty coming up with lyrics for 3 songs on the album. I submitted my ideas for 'Fallin' In Love,' 'Winners & Losers,' and 'Love Is.' Danny loved the lyrics and I had my first hit record, 'Fallin' In Love.'"

In 1974, Playboy records signed the group. This song became the first and only #1 hit for the label.

Until the band had a hit with this song, they were considered as one-hit-wonders, as the rest of their other singles that followed their other Top 40 hit, "Don't Pull Your Love (Out)" (for the Dunhill/ABC label), went nowhere.

In 1973, Tommy Reynolds, the band's drummer, quit to join a band called Shango and was replaced by Alan Dennison.

In 1974, the band signed with Playboy Records, who insisted that they keep their original name (apparently, Playboy thought it would be foolish to jeopardize the very small impact that they had in music).

After the success of this song, they changed their name to Hamilton, Joe Frank & Dennison to reflect the new lineup more accurately.
