Acoustic troubadour David Mallett has extended an invitation for audience members to bring their ukuleles. Folks with ukuleles will have an opportunity to join Mallett onstage for a couple of numbers, including "Garden Song."  Mallett was working on his family's farm in Maine when he wrote his signature tune that has been called an American classic and covered by numerous entertainers, including John Denver and the Muppets. Anyone who is not playing the ukulele at this show ought to be at least inspired to sing along. Jeff Riales opens.

David Mallett performs on Saturday, December 6, at Café Veritas at First Unitarian Church, 220 South Winton Road. 7:30 p.m. $10-$18. cafeveritas.org; davidmallett.com.
