Members of Colonial Spirit Chorus in Acton, MA participated in setting a
Guinness World Record recently in Nashville, TN.  Heather Mullins, Linda Green,
Pat Marais, Norma and George Murray were there as Sweet Adelines International
President Peggy Gram led 6,651 people in the largest singing lesson ever.  I've
enclosed a link below so that you can hear and see part of the lesson (click on
the player at the end of the page) where we extended our hands out to each side
of our mouths until we are able to fill the space with sound.  It was amazing to
hear the sound grow as we all practiced that in the lesson.
