M2dude,
bingofuel,
There's a very good and detailed write-up about that occasion in "Flying Concorde" by Brian Calvert (p.184-185 in my copy).
V1 - rotate - gear up - 100 ft - roll 25 degrees of bank on - and there it is.
And yes, it was one more illustration of the handling qualities of the aircraft... Many of the pilots liked to hand-fly it on occasions where that wasn't really necessary.
And it could be barrel-rolled just dandy.....

Nick,
100ft AGL was standard for that procedure.
