Seems a bit odd to me. Ignoring for a moment that "drummers" at football are more wrong than the wrongest thing on earth, if most people who want to sing are going to be in blocks 110-113, why put the drummers, who I presume try to instigate songs, 4 blocks away
Now hang on, they had the lyrics of GOSBTS printed on the back, so they did have a little street cred.
Reading = Rumblesticks (those stupid inflatable tubes that don't actually make ANY noise when you hit them. Or Opera singers before kick-off (oh dear, haven't we done that as well?)
