Bali is the largest Hindu enclave in Indonesia. It is perhaps the most favourite tourist spot there, a must visit for foreigners especially westerners. On the flight to Jawa Timur to visit the apple country, Malang in 1991, I made a stop over at Kuta, Bali. That was the only visit till now and no chance to witness the ketjak dance.
Apparently, ketjak is a popular traditional dance at temples. The use of frangipani flowers (bunga kemboja) in the hair dress or above ear lobes is a common practice among islanders in the Malay Archipelago and Austronesia.
Train them young.
