Plumduff is a folk band that performs sea shanties and Celtic folk songs. In January 2022, Plumduff entered into an oral contract with Donniegale, an Irish-style nautical themed pub, to perform in February 2023 for a total of ten nights (five nights in each of two weeks) at Donniegale for $2,000 each night, paid by check at the end of each week.  The first night went well as the pub crowd was very happy with the performance. The next night, the pub was packed. Donniegale is a large pub that could accommodate nearly 400 customers. On nights with entertainment, Donniegale earned a cover charge as well as the food and beverage income stream.  On the third night, the pub was full to capacity with a line halfway around the block. At the last minute before Plumduff’s performance was scheduled to start, Plumduff’s lead singer demanded an extra $1,000 for each remaining night (7 nights). The crowd was getting restless and chanting the band’s name. Donniegale’s manager agreed to pay the extra $1,000 per remaining night and signed a memo promising to do so. The manager had authority to enter into and modify contracts for the pub.  At the end of the first week, Donniegale’s manager gave Plumduff a check for $10,000 (the amount in the original contract) and refused to pay the extra $3,000 agreed to in the memo. Plumduff refuses to perform the second week and sues Donniegale. Discuss.
