About Us

A Holiday Affaire has been in existence since 1991. The group started with four singers singing for small parties in the home and has grown to over 30 singers, with more than 50 events per season. We sing for corporations, home holiday parties, and the Manhattan Beach Downtown Open House and Pier Lighting. This group has been featured in the Fox News Annual Hospital Charity Event. The individual singers come from all over the Southern California area, and can be found singing with the LA Music Center Opera, the Los Angeles Master Chorale, and numerous other performing groups.

Ms. Grennan has been singing professionally since 1988. She began her career in opera after graduating with a degree in voice from CSU Northridge. She has performed in musicals throughout Southern California, Europe, and Japan, as well as soloed with local symphony orchestras.  Her foray into jazz began in the mid-1990s, which led to the making of two cd recordings, available on cdbaby.com.
