Grammar: Sing

Carl sings beautifully when he has the chance. And he has the chance often. He sings gospel, and he practices regularly. He sings with his church choir, but he also sings in a private group of friends on Friday nights. They sing anthems and hymns, and they also sing their own songs a Capella style. Since he sings together with other people he does not feel shy. However, he sings with such a nice voice, that he could sing solo and be quite successful if he wanted to.
