Read and answer. 

My name is Nam. It was my birthday last Sunday. I invited some of my classmates to the party. They gave me presents like comic books, robots and teddy bear. We ate cakes, sweets, fruit and ice-cream. We drank fruit juice. We sang English and Vietnamese songs. We dance, too. Phong played the guitar and Linda played the piano. The party ended at 7 p.m. We enjoyed it very much. 

What did Phong do at the party?
