WILLIAMSTOWN -- WGBY-TV is currently in the middle of broadcasting its popular "Together in Song: Season 4," vocal competition show, and the Mount Greylock Regional High School Choir is on it.

Twelve Mount Greylock students, under the direction of Kate Caton, were involved in the taping of the segment, which airs this Saturday at 8 p.m. The episode will also feature four other New England youth and adult choral groups.

Viewers and judges can now vote for their favorite groups.

The area's top choral groups - totaling more than 1,000 performers - compete in five categories each week. The finalists in each category will advance to the Together in Song Regional Choral Awards, to be broadcast live on April 27.
