Whirlybird,
Forget the sun, this is the UK your talking about
Flying around without an ASI really is no great shakes, as long as you have a horizon of sorts, and a few hours on type, say 10+
Concentrate on the picture outside and attitude, ensure your reference point point for landing remains constant with the aircraft configured for landing, and stay with the same power settings you have always used for all phases of the approach.
My only extra advice would be to fly a higher / wider circuit than normal to allow plenty of time for anything you feel unhappy about to be sorted out, feel etc, oh! and dont be frightened to go around with no ASI either, especially if the hedge is rapidly approaching on the approach, becuase it is highly likely you were way to fast on the first approach, if this happens keep the climbout to max of 10degrees above horizon, with full chat so that there is nearly no chance of stalling, settle down, set it up, and collect your medals from the bar afterwards!
Feel free to shoot me down,
