It might not be Cougarmania, but it isn't far off.
The Cougars pounced on a lifeless Eagles side in a scintillating drubbing of their bogey team by 44 points to 12.
In a reverse of January's nightmare trip to the Don Valley Stadium, the Cougars played out a rampaging, entertaining and powerful game in the late evening sun.
Danny Fearon was imperious, Max Tomlinson mercurial and Adam Mitchell reliable as Keighley played their best rugby of the year.
A disappointing crowd of under 1,000 turned out for the re-arranged game, but they will flood to Cougar Park if Gary Moorby's boys do this again next Sunday.
"I am over the moon," said the coach, wearing his broadest smile of the season.
"That was a terrific performance and has erased all memory of the 60-point defeat.
"This game was a benchmark of how far we have come in six months.
"There are some delighted people in that changing room, the lads were magnificent."
Tries from Max Tomlinson, Chris Hannah, Simeon Hoyle, Oliver Wilkes, James Rushforth, Karl Smith and Oli Marns did the damage
