Invite for the TV Mass in Channel 5

Yesterday, I received a txt from CJ of Jesuit. She was inviting us for a taping for one of their TV masses on 21 June 2009, 10AM or 3PM. I told her I would ask the group first (hehehe).
But she called me up this morning, asking for our response. Told her we have not discussed it yet. Honestly, I am a bit hesistant because some of the choirs they have invited were Hangad, Bukas Palad, Ateneo boy's choir (medyo bigatin eh!). We also discussed few items like, we only have guitarists and some expectations or if there were requirements.

Please don't get mad, but I decided to decline because of the short notice. I felt we needed to prepare and practice more. Though I told CJ, we were willing to participate and that if she could just schedule us next month (hehehe). I hope she would contact me again. It'll be great if we could sing on national TV (khet nde live!)
