The Egyptian singer Umm Kulthum hosted a public celebration for the officers' return despite reservations from the royal government, which had been pressured by the British to prevent the reception. The apparent difference in attitude between the government and the general public increased Nasser's determination to topple the monarchy. Nasser had also felt bitter that his brigade had not been relieved despite the resilience it displayed. He started writing his book Philosophy of the Revolution during the siege.
Output:
What Egyptian singer performed at the return of Nasser's brigade?
