Renditions of United, United and The Red Flag brought an essence of the matchday atmosphere to the proceedings. The traditional song that's heard every year under the Munich clock, The Flowers of Manchester, was then sung before the crowd dispersed.
Inside, the memorial service continued with Rev Boyers handing over to broadcaster and United supporter Eamonn Holmes. He interviewed a succession of attendees including Reds legends Sir Bobby Charlton, Harry Gregg and Nobby Stiles, journalist David Meek, current academy coach Paul McGuinness and UEFA general secretary David Taylor.
Also in the congregation were crash survivors, relatives of the 23 victims, ex-players from the Munich era and beyond, and current club staff from Sir Alex Ferguson and David Gill to players including Gary Neville, Ryan Giggs and Paul Scholes.
Meanwhile, hundreds of United fans attended a service at the crash site in Trudering, near Munich. Flowers were laid at a commemorative plaque.
