Bryan Adams said in the Daily Mail March 7, 2008 about this song regarding the unexpected finding of love against all expectation: "It's about keeping an open mind. I don't think I've seen everything at all."
This was co-written by Robert "Mutt" Lange. Lange had previously co-written a song of the same title with Huey Lewis for his then wife Stevie Vann, which she recorded on her 1995 self-titled album. Because of questions that arose because of this co-incidence, Adams was forced to confirm on his website that this was a completely new composition and that the title and Lange were the only similarities to the song.
"Sloop John B" is a traditional West Indian folk song, and it was a huge hit for The Beach Boys in 1966. They tweaked the lyric, "This is the worst trip since I've been born" to "...I've ever been on" as a wink to acid culture.
"Kickstart My Heart" is about all the ways Motley Crue gets their blood flowing without drugs. It was inspired by their bass player Nikki Sixx, who claimed he had to be revived with a shot of adrenaline to the heart after an overdose.
