Celeste,
I've asked my dad but too bad he did not participate with the chanting for many yrs and had lost the contact with the fellow friends.
I've checked with my friend, she says u must be 1 of the member of the temple so that u can arrange for those group chanting. If not, can call up some temples to check if they provide this service. eg. ju shi ling, or kuan ming shan.
My friend gave me a hp no. 91886728 (name: su chan), she says can check out with this person whether he/she can arrange it cos 1 of the friends ever engaged them. I tried calling that no. just now but the hp is off. i hope pauline can manage to contact the person.
