FDNY pipers bag 50 yrs.

The FDNY’s bagpipers — 100 members strong, each an active-duty firefighter — are celebrating their 50th year of performing at parades, memorials and other events in the five boroughs.

The band — and alumni — will celebrate its semicentennial at Citi Field today.

After 9/11, when 343 firefighters died, the Emerald Society Pipes & Drums played at 24 funerals in a single day that none will ever forget, said Drum Major Capt. Liam Flaherty.
