Play once as an intro and then these just repeat throughout almost the whole song, he only time these shiny be played is when they repeat "Up all night, hey, up all night..." And during the bridge when Harry sings the chorus and the rest echo "We're gonna wanna stay up all night..." start out quieter and gradually get louder until the main chorus and play louder. Enjoy! :) -Grace Guitar 1/Bass Guitar E|-----------------------------------------------------------------| B|-----------------------------------------------------------------| G|-----------------------------------------------------------------| D|-----------------------------------------------------------------| A|-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-| E|-----------------------------------------------------------------| Guitar 2: E|-----------------------------------------------------------------| B|-----------------------------------------------------------------| G|-----------------------------------------------------------------| D|---------------------------------2-2-2-2-2-2-2-2-3-3-3-3-3-3-3-3-| A|-3-3-3-3-3-3-3-3-5-5-5-5-5-5-5-5---------------------------------| E|-----------------------------------------------------------------| Guitar 3 (main tune) E|--------3----------3----------3------------------3----------3----------3----------| B|-----------5----------5----------5----3-------------5----------5----5-------------| G|--5--5----------5----------5---------------5--5----------5----------------5----4--| D|----------------------------------------------------------------------------------| A|----------------------------------------------------------------------------------| E|----------------------------------------------------------------------------------|
