bash script looping

[Rodney Kanno]

I need some opinons on loops....for the following script, I would like to add 
one while loop. What's the best way to do this? If I can get this to work, 
the this will be my first script...hopefully its not too complicated.

Thanks,
Rodney


#!/bin/sh
#
echo ""
echo "Please choose one of the following options:"
echo ""
echo "[N]ormal retrival, just tracks & title via CDDB."
echo "[E]xtended track retrival + normal retrival via CDDB."
echo "[A]dditional text retrival + normal retrival via CDDB."
echo "[T]otal retrival, all options above retrived via CDDB."
echo ""
echo ""
echo "[M]ake Template."
echo ""
echo ""
echo "[C]onvert Template to cover."
read action
case $action in
	N|n)	echo "Normal retrival....."
		disc-cover -a " ";;
	E|e)	echo "Extended track retrival + normal retrival..."
		disc-cover -e -a " ";;
	A|a)	echo "Additional text retrival + normal retrival..."
		disc-cover;;
	T|t)	echo "Normal, Extended, Additional retrival..."
