Apple Logic Pro /LogicExpress Discussion

I have made a recording of an opera singer for a song I'm working  
on. The singer is excellent but I am trying to soften the sound of the  
vocals (less harsh, not quieter) but without making the sound too  
processed. I only have logic 9 to work with and I can't re-record the  
vocals.

Anyone got any tips please?

Thanks in advance
