The 6 Basses sang the National Anthem for the Quakes game Saturday August 16, 2014. Apparently the singing worked as the opposing team lost.

In this scripture, the commander asked his troops to start singing as the approaching army got within hearing distance. What was the problem, you ask? Either the Lord was in their singing or the opposing soldiers killed themselves because they could not stand the noise.
And when they began to sing and to praise, the LORD set ambushments against the children of Ammon, Moab, and mount Seir, which were come against Judah; and they were smitten.
2 Chronicles 20:22
