Bird invites kids to sing for the King
After releasing Tam Roey Pra Ra Cha (Follow The King's Steps), the superstar Thongchai "Byrd" McIntyre invites Thai children nationwide the chance to join him in singing the song online through Google+ Hangouts, and participate in a group chat on Jan 13, to celebrate Children's Day.

Participants are encouraged to choose between two activities. The first choice is to sing Tam Roey Pra Ra Cha as a group or individually and then upload a video clip of it to Google+, or send it by text to #Tam Roey Pra Ra Cha. Those interested can practise singing the song at
www.gmember.com.
The second is to send a message of their resolutions on how to follow the King's footsteps by writing their name followed by #Tam Roey Pra Ra Cha at
http://gplus.to/TheKingFollower.Submission of video clips and messages will close on Jan 12. Entrants behind the nine clips with the most votes will be selected to accompany Byrd in singing the song.
