These days both men are still heavily involved in the professional game and will be taking part in this weekend's Heineken Cup quarter-finals. Humphreys is director of rugby at Ulster, while Galthie is head coach at Montpellier.
Both clubs have to travel away in the last eight - Ulster head to Twickenham Stadium to face Saracens while Montpellier go to Stade Marcel Michelin to tackle ASM Clermont Auvergne - but will miss each other in the semi-finals if they win. That means Humphreys and Galthie are two steps away from another Dublin clash.
Their first meeting came in the year the English clubs boycotted the tournament. Ulster beat Toulouse twice and then Stade Francais to reach the final, while Colomiers reached their only final final to date by beating Munster and Perpignan in the knock-out stages.
A record crowd of 49,000 packed Lansdowne Road hoping to see an Irish province be crowned champions of Europe and six penalty goals from Simon Mason and a drop goal from Humphreys earned them a never-to-be-forgotten 21-6 victory.
Humphreys was at the helm when Ulster reached their second final last season, losing to Leinster at Twickenham, and Galthie has also had experience of guiding a team to a second final. That was in 2004/05, when he was coaching Stade Francais Paris, who were beaten in extra-time by Toulouse in Edinburgh.
Galthie got his hands on an Amlin Challenge Cup winners medal when he was a try scorer for Colomiers in their 45-3 victory over Agen in 1998 and one of his team mates that day, David Skrela, is currently in the Clermont squad. Skrela also featured in the 1999 final in Dublin.
The 18th Heineken Cup Final at the Aviva Stadium on Saturday, 18 May (kick-off 17:00) will be the third time the event has been staged in Dublin. After Ulster's famous victory in 1999, two French teams clashed at Lansdowne Road in 2003 with Toulouse beating Perpignan 22-17.
