One year before he was reunited with Cheers regular Kelsey Grammer on Frasier, John Mahoney guest starred on Grammer's earlier series as Sy Flembeck, a hack songwriter hired by Rebecca (Kirstie Alley) to compose a jingle for Cheers. As for the main plot of this episode, a pregnant Maggie (Annie Golden) returns and insists that Cliff (John Ratzenberger) is her baby's father. Meanwhile, mercurial ex-convict Andy (Derek McGrath) pops up at the bar, looking for the long-departed Diane Chambers. ~ Hal Erickson, Rovi
