I am thinking about having a string quartet for the wedding. My step-mom is a music teacher and knows a lot of people who could do this for me. I wanted the quartet to play for the ceremony and maybe into the cocktail hour. I know certain vendors are to be fed (feeding dj, photographer and officiant). Do I need to invite the ceremony musicians to the reception, feeding them dinner, as well? (I am still undecided about them playing during the cocktail hour... not sure if that will affect the advice I am given.)
