How Many Carolers Does It Take To Break A World Record?

Update appended — Warm up your vocal chords, Boston Pops Conductor Keith Lockhart and the Tanglewood Festival Chorus want your help Saturday in their effort to break the Guinness World Record for the largest group of carolers singing in one place at one time.

The Tanglewood Chorus has 300 vocalists. Multiply that number by about 27 and you get the picture of what Lockhart is hoping to create — right at noon — outside Boston's Prudential Center.

“I would like to shatter the record and not just beat it,” Lockhart explained with a competitive, but amused, edge in his voice, “so I think we need 8,000 people."

The current record is 7,514 carolers, held by Bob Jones University in South Carolina.

To win a place in the record book Lockhart's massive mob will sing nearly 20 songs continuously for 15 minutes.

When asked which songs they'll be singing, the conductor said, “I think the question is more likely to be what songs we won't be be singing ... And to that, I can answer we probably won't be singing 'Grandma Got Run Over By A Reindeer.'”

Guinness World Record officials will be on site to confirm the caroler count.

The event kicks of the holiday concert season for the Boston Pops.

Update: The bid failed, attracting just 3,239 carolers on Saturday.
