K-Town Sound Show Chorus Quartets

Masquerade Quartet is a dynamic ladies quartet singing a cappella music in the Barbershop style. We believe in sharing our love of this style of music with any audience we can find. This fun-loving quartet consists of Tenor—Patricia Mastro, Lead—Lisa Holland, Baritone—Pamela Jett and Bass—Kelly Ogle. 

Originally formed in Fall 2019 with Tenor Deborah Latham. Deborah decided to step down as our tenor due to family obligations. So, we found a new Tenor, Kathy Yonka, in Fall 2021. Unfortunately, she too stepped away from our quartet due to family obligations in the fall of 2022. We were blessed to find Tenor Patricia Mastro who jumped right in so we could continue our quarteting journey. 

Now Masquerade 3.0 is better than ever and even winning the Most Improved Quartet award in our region for 2023. We are proud to be representing all our choruses; KTown Sound, Scenic City, and Harmony Hills. We value your friendship and support as we strive to be the best we can be.

"The Sapphires" formerly Southern Sapphire changed their name in July 2025. The name change came about after they walked into a historic Victorian House to sing Christmas Carols and they heard the volunteers shouting with glee, "The Sapphires are here!" This quartet has been singing together since September of 2023. They are having a wonderful time and are available to sing at special events year round including Birthdays, Club Meetings, Singing Valentines, and Christmas events.

Janet Brockman. Baritone. Janet has been a Sweet Adeline since 2012. Singing Baritone fits right in with her personality. She sings the leftover notes in barbershop, just like she eats leftovers at home.

After transferring to the Knoxville, TN area, She joined Smoky Mountain Harmony chapter until they folded in October 2012. Work got in the way for a while, but when work eased up in July 2014 she joined K-Town Sound Show Chorus, and currently serves as their President.

She’s competed regionally numerous times, earned several medals, including first place with Rio quartet in Region 11 (California) in 2007.  When she moved to Tennesse, she thought she was done with Sweet Adelines. Boy was she wrong! She currently co-directs K-Town Sound Show Chorus and loves teaching singers how to be better. Diane says "...it’s a blast to be quartetting again!"
The quartet and the chorus is lucky to have her!
