Troy,
In the late '50s, WFIL-TV (now WPVI-TV), Channel 6 in Philadelphia, would drag its sole TK-41

from its studio at 46th and Market to Broad Street near City Hall and broadcast the mummer's parade live. When they may have begun to tape the event however, I cannot say, but parts of the parade were shown on their evening news. WFIL was the first station to originate live color in Philly. Perhaps some B roll exists, but that was a long time ago.
