Part of the song is set to an arrangement of part of the tune of "With cat-like tread", from the 1879 Gilbert and Sullivan comic opera The Pirates of Penzance, with lyrics adapted from the American song "Hail, Hail, the Gang's All Here".
The "It's a grand old team" section, however, bears no resemblance to "With cat-like tread".
However, the original version, played at Parkhead, was recorded by Glen Daly in 1961.
[2][3] To mark the 50th anniversary of the original release, Shane MacGowan recorded his version in 2011.
Sure it's the best darn team in Scotland, And the players all are grand, We support the Celtic, As they are the finest in the land we love them, We'll be there to give the Bhoys a cheer When the league flag flies, And it cheers us up when we know the Scottish Cup, Is coming home to rest at Paradise.
