The 70-member band finished behind Thailand's Ratchasima Witthayalai Marching Band in the marching show band category with 88 points, 2.5 points shy of the winning score, during the competition on June 30.
"We're indeed very proud of their achievement. I noticed my granddaughter spent a lot of time training, even the whole day on weekends, so I hope their victory will teach them that to succeed, it needs a lot of effort, training, patience and hard work," he said when welcoming the band members home at Kuching International Airport on Thursday night.
"Finally, we got a gold medal and second place out of 20 teams," he said, adding that the band learned to bond together as a family during their time in Germany. The European Open Championship on June 28-30 was part of the International Music Festival in Rastede, Germany.
