NYRA's Youtube page has added 3 old races including John Henry.
There are a lot of his other races already on Youtube, but a few of these races are pretty interesting.
They include Darby Creek Road's allowance win at Saratoga where he set a still-standing track record of 7 furlongs in 1:20.40

Darby Creek Road also got the best of John Henry on turf here in the Hill Prince:

He had a 3-for-3 lifetime record against John Henry, though he did meet him before the gelding started to reach his peak.
