Let Your Love Flow home on a waterslide, a metaphor for the ease with which the card may be used. The ad was first aired 25 October 2008, and two weeks later "Let Your Love Flow" re-entered the UK Top 100 singles chart dated 8 November 2008 at #48, with the track eventually peaking at #21 over a six-week tenure with subsequent UK chart tenures of five weeks in February/ March 2009 (peak #48) and three weeks that summer (#76). Speaking for the Bellamy Brothers, David Bellamy would state: "We had no idea the song 'Let Your Love Flow' had been licensed to Barclay
Who You Love that his relationship with Perry has been a private and "human" one. On writing the song, Mayer said: "Who You Love" is a sweet melody that tells the story of opening your heart up and allowing yourself to fully love the person in your life—or specifically to "love who you love, who you love." "It was a really great experience and the song is one of these like old FM '70s and '80s sort of like duets, and I listened back to it; it's, like, really convincing. And I watched it get made and I'm still kind of taken aback."
