Two former members rejoined American Babies during a post-Furthur show at New York’s Ace of Clubs this past Sunday. Guitarist Scott Metzger sat in for most of the evening, including a notable take on The Band’s “Lookout, Cleveland” and an extended version of the Babies’ “Winter War Games.” In addition, Furthur drummer Joe Russo guested on a number of the tunes from his tenure with the group: “Invite Your Friends,” “Brooklyn Bridge,” and “American Babies.” Metzger also was on stage for a cover of the fittingly-titled “Further On Up the Road,” as a bit earlier in the night the guitarist and American Babies frontman Tom Hamilton were among those who attended Russo’s Furthur performance at Madison Square Garden.
