Either an item found in the area you unlock with the crowbar, being either a tophat or a bowtie (note: having both items gives you 2 scenes total). For rest of the scenes, you purchase the items on BooBay and get caught after buying them
When you buy the crowbar, you use it on the barred doors near the stage (place where Frennie uses the cameras). They show up on the item finder if you have having trouble seeing them
