Love of a Lifetime (FireHouse song)

"Love of a Lifetime" is a song performed by the American rock band FireHouse. It was the band's third single and its highest-charting single in the United States, entering the Billboard Hot 100 June 29, 1991 at No. 81 and peaking at No. 5 the week of September 28, 1991. It is also the band's first and most popular power ballad. The song was written by vocalist C. J. Snare and guitarist Bill Leverty.

The song is arguably what FireHouse is most known for, and has been used as a first dance song at countless weddings since its release. In a 2005 interview, Snare commented "now I have the benefit of time to look back over this and there isn't a show that goes by where people don't come up to us and are like "'Love of a Lifetime' – we got married to that song!"
