Mozart, widely regarded as one of the greatest classical composers of all time, wrote his first symphony at age eight and was dead by the age of 35. Schubert also died when he was 31, while Chopin famously didn't live past the age of 39. Moreover, the phenomenon of the castrato in classical music in the 1700s shows that young people haven't just been interested in classical music throughout the years - they've practically been canonised as part of a classical music tradition that, although lost, is not forgotten.
Today's orchestras, choirs and opera houses are packed with young singers and musicians, many of whom are still in their twenties. Moreover, almost all modern, successful classical musicians will have undergone training from a very young age. Charlotte Church may have made headlines when she released her debut album "Voice of an Angel" in 1998 aged just thirteen, but while her phenomenal mainstream success was not typical, the fact that she was such a young musician in the classical industry was.
In the twenty-first century, the likes of Katherine Jenkins and "male soprano" Michael Maniaci, 28 and 29 years of age respectively, are making headlines the world over for their innovative approach to classical music and their stunning vocal range. Edward Gardner, the new Music Director of Glyndebourne on Tour (one of the UK's premier operatic fixtures), is also only 28, proving that there is certainly no dearth of young people performing classical music, although there may be fewer youths than OAPs listening to it.
