By the end of a superb campaign, however, the Exiles had achieved fourth place in the Zurich Premiership, reached the semi-finals of the Parker Pen Shield, qualified for the Heineken Cup and, most impressive of all, conquered Northampton to lift the Powergen Cup.
Is it greatest day in the club’s history? Well, it is the only serious piece of silverware Irish have won to date and what stood out was the manner of a sublime performance that saw a Saints side brimming with internationals swept away without trace.
Some 75,000 fans, the majority clad in London Irish colours, were present at Twickenham, and how they partied as the Exiles built an unassailable 24-0 half-time lead before scoring five tries in all during a feast of attacking rugby that defied their underdog status.
Geoff Appleford and Justin Bishop notched two tries apiece, while Mike Horak weighed in as well, but replacement lock Glenn Delaney, now back at Irish as forwards coach after a nine-year absence, pinpoints the real hero of that heady afternoon.
“Our player-coach, Brendan Venter, set the tone unbelievably that season and that led us from being a good group of players to being a great team, which culminated in that fantastic win over Northampton,” Delaney recalls.
“We’d been written off that year but that was great for us because there’s nothing better than playing with a chip on your shoulder – and we certainly had that!
“We weren’t fashionable, we weren’t trendy, but what we did have was character. We had players who’d played international rugby, like Brendan and Naka Drotske, but they weren’t what you could describe as superstars.
“What we had, though, was energy, enthusiasm and a real desire for work. Brendan drove that and was also very innovative by bringing in the ‘out-to-in’ defence which no one had ever done.
“It was a wonderful time and, as a team and a squad, Irish was a really enjoyable, hard-working place to be. It all just came together that day.”
Northampton found themselves on the back foot early as Appleford sliced through a non-existent defence, before further tries from Horak and Bishop, along with a Barry Everitt penalty, made it 24-0 as the half-time whistle approached.
Stung into action, Saints set up camp on the Irish line. But there was no way through and as the teams returned to the dressing rooms, the Exiles knew the game was won.
Delaney said: “Funnily enough, the highlight of that game was probably that five-minute period of defence when the team just made tackle after tackle. Saints went away with nothing and that was a really big moment.
“Then seeing Saints captain Budge Pountney and Matt Dawson having a bit of a scrap was great because we knew we’d got them. That summed up the character of our side.
“Chris Sheasby was immense that day as a ball carrier and all 22 players played their part. To this day, it remains one of the best team performances I’ve had the privilege of being involved with.
“Northampton were coached by Wayne Smith and 14 of their starters were internationals, while we were just little old London Irish. But we did it for our fans who were absolutely brilliant.
“We had a good few beers after that… and didn’t win another game all season!”
