The Children's Philharmonia of Szentegyháza comprises a total of 140 members between the ages of 10 and 20, including 100 choir members and 40 young musicians in the orchestra. Their repertoire consists of well known classical pieces from the likes of Bartók, Handel, Weber, alongside specially orchestrated folk songs from Hungarian and other cultures, as well as historical songs.

The ensemble, affectionately known as the Fili, has been performing regularly since 1990 and participates in international tours every summer. The children proudly perform in traditional Szekler costumes, preserving and protecting their ancient Hungarian heritage.

In December 2003, Sándor Haáz and the ensemble were awarded the "Prize for Preserving Hungarian Heritage".

Their exclusive appearance in London will follow two special headline concerts in Manchester, as part of Góbéfest, a festival of culture from Transylvania, The Carpathian Basin and Eastern Europe, taking place in Cathedral Gardens from 23- 25th of June
