Thank you for your comments. "Benguet was formerly a sub-province of the old Mountain Province and became a separate province with the enactment of RA No. 4695 on June 18, 1966." [www.igorotage.com/blog/p/Y4Nzw/benguet-history]
Also, the interpretation of this dance was based on the dance literature published by the Philippine Folk Dance Society in their book, "SAYAW Dances of the Philippine Islands Volume 6" with National Artist for Dance, Ramon A. Obusan as the dance researcher with Susana Bagne as resource person in its 1983 National Folkdance Workshop. Should you need a copy of the dance literature, please feel free to email us at sambitngcbsua@gmail.com. Once again, maraming salamat po. God bless.
