Canterbury Clothing Company. Before the start of the 2004–05 season, the 'Lions' was dropped from the name. It is still used for marketing and branding, in particular, the Cubs Club for Junior members of Leinster Rugby. The Leinster mascot is "Leo the Lion". It was also during this time that the song “Molly Malone” became a match fixture to be sung by the fans. Leinster's first season in the newly formed Celtic League ended in success as the Lions were crowned the inaugural champions, beating rivals Munster Rugby in the 2001–02 final. In 2002–03, they became only the third team in the history of the European Cup to win all their games in pool play. They also went one step further in the playoffs than the previous season by reaching the semi-finals (for the first time since 1995–96), but lost at home against French side Perpignan, which was accompanied by an unsuccessful season in the Celtic League. The 2003–04 season also ended in disappointment as Leinster slumped to their worst ever league performance and failed to qualify from their European Cup group. Title misses (2004–2007) Leinster improved during the 2004–05 season, finishing 3rd, just three points behind the eventual winners, the Ospreys. Leinster also won all of their pool games in that year's European Cup, and were again among the favourites for the title, however they went out at the quarter final stage to Leicester Tigers. The next two seasons of the Celtic League were to end in near misses for Leinster, as they lost out on the 2005–06 and 2006–07 league titles on the final day of the season. These seasons also saw progress in the European Cup. In 2005–06, Leinster progressed to the semi-final but were eliminated by Irish rivals Munster at Lansdowne Road and they reached the quarter-final the following year where they were beaten by eventual winners London Wasps. European and domestic dominance (2008–2014) Increasing attendances at Leinster games led to a move across Dublin 4 from Donnybrook Stadium to the redeveloped RDS Arena. In 2007–08, Leinster failed to qualify from their European Cup pool, but did end the season as Celtic League champions, sealing the title with a 41–8 victory over the Newport Gwent Dragons in front of their home fans at the RDS. In the 2008–09 season, Leinster topped their European Cup pool despite away losses to French side Castres and English side Wasps.
