I always think of an episode of New Girl when I hear this song. Jess and her roommates get invited to a wedding and Nick is afraid of falling for his ex-girlfriend, Caroline, again. At the end of the episode, Jess and Nick dance to this song. If I remember correctly, the episode was featured on my Aer Lingus flight to Ireland.
A Groovy Kind of Love was originally released by The Mindbenders in 1965. In 1988, Phil Collins re-recorded it for the soundtrack of Buster, a British comedy/drama film in which he starred. The single went#1 in the United States, Canada, Ireland, Italy, United Kingdom, and Sweden.
