• This song about a reunion with a lost love is Moore's favorite track on Up All Night. "It's about running back into someone that you haven't seen in a years and you always had such a strong connection with and you're right back in that place," he explained to The Boot. "The bond between you two will always be there."
• The idea for "Crazy One More Time" came to Moore after he ran into someone he was once close to whom he hadn't seen in years. After coming up with the guitar riff, he had a dream about the song a couple of months later. "The lyric was there," Moore said, "and I woke up with the lyric at 2 o'clock in the morning and wrote it all out."
• Moore co-wrote the song with Chris Lindsey and Aimee Mayo and recorded it for his 2012 debut album, Up All Night. It became a fan favorite, so a decade later he re-recorded "Crazy One More Time" and released it to radio on January 3, 2021.
