An overflow crowd of more than 250 people commemorated the 15th anniversary of September 11 by attending an outdoor concert, Sunday afternoon, in the City of Fairfax’s Old Town Square. Performing was the U.S. Navy’s acclaimed jazz band, “The Commodores.” Residents, visitors and even several members of the City’s fire department enjoyed hearing cool jazz on a hot, summer’s day. The musicians played popular jazz songs, patriotic tunes and the anthems of each branch of the U.S. military.
