T-Bone is watching TV with Sheriff Lewis. Sheriff Lewis is about to switch it off to read T-Bone a book, but he sees that T-Bone is enthralled by the music playing on the music station that he has on. T-Bone gets up and dances. He fantasizes about being part of his own band. The next day, T-Bone is over with Clifford's. He tells Clifford about how great the music is and how he wants to form his own band. He's even started writing a song. Clifford says that sometimes Emily Elizabeth has that music channel on also and he likes the music as well. Cleo comes also and they all start working on the band. Clifford wants to play drums and Cleo is dancing. Then, Mac comes along. He wants to join in too and T-Bone, Clifford and Cleo are more than happy to let him in. He even comes up with a name for the band: the "Pack Street Dogs." At first, Mac tries to join in as a singer. But he's bad at singing, really bad. He claims he's just not suited to sing the type of song they're singing. So they try moving him over to the drums with Clifford. But he beats the drums completely out of tune and that doesn't work out. Then, everyone has to go home for dinner. The next day, they start work on the band again. This time, Mac tries to join Cleo in dancing. But he's not matching Cleo's moves and his trying to do his own dance and it's just not working. He's beginning to think he doesn't fit into the band and suggests maybe he shouldn't be a member, but Clifford, Cleo and T-Bone aren't about to let him out that easily. If he wants to fit into the band, they'll find a place for him. As it turns out, T-Bone's been having trouble writing more lyrics for their song. But it turns out that Mac is great at lyrics and so he becomes their songwriter. They practice hard and then give a concert for all the dogs on the island. All sorts of dogs have turned out, including K.C., Rexington, Mimi, Kiki, Oscar, Frankie, Mannie, Tonya, Bob, Susie, Hamburger, Macie, Harriette, and Artie. Even kittens Billy and Betty are there. They sing a rather long song about caring about your friends and everyone loves it.
