First seen in the episode "Dude, We're Getting the Band Back Together", the group had broken up due to infighting and having smaller and smaller crowds, but thanks to one boy, due to his father and mother not remembering their date, he was able to get them back together and perform a song for them, with almost everyone in town, including "ninjas of love" coming down the stage, who had built it earlier in the day. The band also appeared in "Thaddeus and Thor" singing with Dr. Doofenshritz about his mom not liking him due to him not being able to kick. In "Phineas and Ferb:Summer Belongs to You!", Love Handel did two songs:Bouncin' Around the World and one for the Klimpaloon, called "The Ballad of Klimpaloon", which is only on the soundtrack. On the Phineas and Ferb Holiday Favorites album, they sung 'Santa Claus is Comin' to Town'. They were younger, but in their current clothes during Carpe Diem in "Rollercoaster: the Musical!"
Lawrence Fletcher bought tickets for himself and Linda Flynn to attend the farewell concert of Love Händel, her favorite band. After they were featured in the "flaming hot spotlight of love", Lawrence felt brave enough hold her hand, which he had never done before. Danny yelled over to him to kiss her. Linda obliged and kissed him passionately; the two were later married. ("Dude, We're Getting the Band Back Together")
Bobbi and Sherman have seen the documentary about their band. During an argument, Bobbi stated that it was "slovenly behavior that ruined Love Händel", while Sherman quoted the "infighting due to pressure from a dwindling fan base" statement from the documentary.
Love Händel have been on a national tour at least once (maybe twice). For, they have mentioned being in Albuquerque in 1993 and Detroit in 1994.
The name "Love Händel" is a mix of two terms, one a slang term for being "a little overweight" around the hips (love handles) and the other making reference to Baroque musician George Frideric Handel who created among other pieces Messiah.
In 1994 in Detroit, though unknown exactly what happened, the band somehow ended up covered in juice and packing tape. Bobbi brought this up after Paul the Delivery Guy helped Perry the Platypus juice D.E.I and the band was left behind. ("Delivery of Destiny")
Songs performed by Love Händel in the show are all sung by Jaret Reddick in real life.
Their name is a reference to Glam Metal.
Arthur "Killer" Kane, the bass player for the New York Dolls (a proto-glam/punk band), found himself working in a library after the band broke up. They, too, later reunited.
