(c) A, a singer, contracts with B, the manager of a theatre, to sing at his theatre for two nights in every week during the next two months, and B engages to pay her a hundred rupees for each nights performance.

(d) A contracts to sing for B at a concert for 1,000 rupees, which are paid in advance. A is too ill to sing. A is not bound to make compensation to B for the loss of the profits which B would have made if A had been able to sing, but must refund to B the 1,000 rupees paid in advance.
