Here's a master track of "Live for Today". The song is near the begining of the Musical, just after the prologue. It takes place during the first therapy session as Denise explains to the group that her husband is the one responsible for driving her to seek consultation. She can't remember the last time they were intimate and now she she goes online to experience her fantasies.
It's sung by Sienna Stock with Mark and Luke Colombo singing backup vocals. You might want to download the Sheet Music for "Live for Today" to follow along.
