i saw this dude on youtube with the name UnclassicalPiano1 who plays songs like Stairway to Heaven, Paranoid, and Purple Rain on piano its his own interpretations so he doesnt have any sheet music, point being is that it is possible to play those kinda songs on piano and im having trouble finding them cuz i have to pay for most of them :( if anyone has any site they would like to share i would be grateful
