Celebrity Celtic fans Martin Compston and Gianni Capaldi and ex-players Alan Thompson and Bobby Petta have been filmed whipping up a crowd of fans who are singing an IRA chant.
The footage, shot at the Celtic Convention currently taking place in Las Vegas, emerged online earlier today.
It showed a huge crowd singing "Irish Republic Army" and "IRA" to the tune of Daniel Boone's 1972 hit Beautiful Sunday.
