3 to do but cannot parse them so explanations as to how you arrived at the answers please.
A) Give a sparkling performance? (9) C?R?S???? I can only think of 'coruscant' but why 'performance'?
B) Band needs drink when travelling round Ulster (5) ??n?a. Pretty sure it's NOT tea + ni = tenia. Band is confusing me.
C) Beam - not right ahead, more towards the stern (5) ????R. Laser? Anger? Aft+er?
All these clues are intersecting so if one is wrong it makes the others wrong.
