Scarves were left on the seats in memory of those who died, and the service began with the singing of the hymn, Abide With Me, which is synonymous with the FA Cup and has been sung at every final since 1927.
Speeches were followed by a rendition of You'll Never Walk Alone, led by the singer Gerry Marsden, during which 96 balloons were released.
During Sunday's match with Manchester City FC, Steven broke down at the end of the game. "The reason I was so emotional was because of when this game fell," said the 33-year-old.
Before the match the stadium fell silent for a minute's silence. 96 seats were left open for those who went to the football game in 1989 and never went home.
