A minute's silence to remember the 66 fans who died in the Ibrox disaster 52 years ago was tarnished by boos ahead of the Ne'erday Old Firm clash.
Rangers announced the tribute earlier this week and Celtic added in a further statement that supporters should also use the silence to remember Parkhead strike legend Frank McGarvey, Pope Emeritus Benedict XVI and footballing legend Pele. The champions also wore black arm bands as a mark of respect, but upon match referee John Beaton's whistle the Sky Sports microphones picked up sporadic shouts from the away end.
Around 700 tickets were issued for the away fans and some noise could be heard from the visiting support before a ball was kicked in Govan. When Beaton sounded his whistle to signal the end of the moment of remembrance a vocal home support booed the response of the Celtic fans before the derby showdown got underway. Sections of the home support then responded with a rendition of the Billy Boys as commentator Ian Crocker stated after the silence "one or two couldn't manage it".
There was certainly no moral high ground for those within the home support who responded with a rendition of the Billy Boys to perch themselves on, though.
Earlier, Parkhead directors joined their Rangers counterparts, including Honorary Life President John Greig, with new Celtic chairman Peter Lawwell standing side by side with Douglas Park at the memorial statue. The tragedy occurred on January 2, 1971 when 66 fans lost their lives following a crush on Stairway 13 with more than 200 people injured following a crush after a 1-1 draw.
