Sunan Ibn Majah 1898

It was narrated that 'Aishah said:“Abu Bakr entered upon me, and there were two girls from the Ansar with me, singing about the Day of Bu'ath.” She said: “And they were not really singers. Abu Bakr said: 'The wind instruments of Satan in the house of the Prophet ?' That was on the day of 'Eid(Al-Fitr). But the Prophet said: 'O Abu Bakr, every people has its festival and this is our festival.' ”
