Time to bust out that Lederhosen. Oktoberfest is coming. The 37th annual Oktoberfest and HONK! Parade in Cambridge’s Harvard Square arrives Sunday, October 11, and while the seasonally-appropriate jamboree features six stages of live entertainment — as well as “dozens of international food vendors, hundreds of street vendors selling artwork, jewelry and vintage clothing, neighborhood sidewalk sales and HONK! bands from around the country!” — we’re most excited for the live lineup curated by Bowery Boston.
