You might have heard a version of “Children Go Where I Send You” on your aunt’s Peter, Paul and Mary record, or at some long-ago weenie roast sponsored by some wholesome youth unit. You might even have heard that it’s a spiritual; it cozies up to “Balm in Gilead” and “Deep River” in the mother of all folk songbooks, Rise Up Singing. But you haven’t heard it played with a Bourbon Street strut unless you’ve heard the Grandsons’ version. On A Holiday Feast Vol. VI, Alan MacEwen bellows the first line and is answered by an army of Grandson brass so holy, you won’t even be distracted by wondering what “the six that never got fixed” are. Tonight, Hungry for Music asks you to bring a musical instrument in good working condition to the benefit disc’s release show—as a donation; no jamming along, please. Join the Grandsons, Jumpin’ Jupiter, the Fabulettes, and more at 8:30 p.m. at IOTA, 2832 Wilson Blvd., Arlington. $10. (703) 522-8340. (Pamela Murray Winters)
