Among the most important Feyenoord songs are ""Mijn Feyenoord"" by Lee Towers, ""Feyenoord, wat gaan we doen vandaag?"" by , and ""De laatste trein naar Rotterdam"" by Dorus. During the 2001/02 season, when Feyenoord won the UEFA Cup, a parody of the song "Put your hands up" by Black and White Brothers was launched, called "Put your hands up for Pi-Air", a tribute to Pierre ("Pi-Air") van Hooijdonk, one of the club's key players at the time. In the 1970s, Coen Moulijn also had a song dedicated to him, "Coentje Coentje Coentje". The supporters of Feyenoord are said to be one of the most loyal supporter groups in the world supporting the team during both good or bad times. They are nicknamed "Het Legioen", Dutch for "The Legion" and can be found everywhere in The Netherlands and far across the Dutch borders. Squad number 12 is never given to a player, but is reserved for Het Legioen instead. Feyenoord is a popular club in the Netherlands with a large number of supporters. The team's first training session of a season alone attracts thousands of fans; 20,000 attended 2007–08's inaugural session. In 1963, about 3,000 fans boarded on two ships, among thousands of others by train or car and they travelled to Lisbon where Feyenoord faced Benfica in the European Cup. When Feyenoord play abroad in European competitions, about 8,000 travel together to support their team. Almost 15,000 fans were cheering for their team in 1996 when Feyenoord played in Germany against Borussia Mönchengladbach. About 40,000 fans visit a regular match at home while top classes against Ajax, PSV and European cup opponents are sold out most of the time. About 250,000 fans showed up when Feyenoord's Dutch championship was celebrated in 1999 at the Coolsingel in the centre of the city. After Feyenoord beat Internazionale in the 2002 UEFA Cup semi-final, Inter midfielder Clarence Seedorf said, "I really enjoyed the atmosphere in the Kuip. As an ex-Ajax player I was really given the bird, but that's all part of the emotions in football. It also illustrates the intense way in which the Feyenoord supporters experience their club's matches."
