Legend has it that Tom Petty wrote the third verse of Mary Jane’s Last Dance while looking down on Market Square from his hotel room.
“There’s pigeons down on Market Square
She’s standin’ in her underwear
Lookin’ down from a hotel room
The nightfall will be comin’ soon”
Who knows if it is true but Tom Petty and The Heartbreakers did play in Pittsburgh frequently and there are usually pigeons in market square. In any case, it is a fun place to spend some time in.
