tamil film song concert

Just came back from a concert of tamil film songs. The standard of singing and playing was incredibly good. They played to a packed house of about 400 people.
The surprise was almost the whole troupe was made up of practising DOCTORS, there were a few consultant anesthetists who were on percussion instruments - they have the time to keep drumming, paediatricians who could sing well - extension of their job of communcating with their patients.
I really wish I could play a musical instrument
