Fleetwood Mac debuted their new lineup by performing ?The Chain? and ?Gypsy? on Wednesday?s Ellen. The televised appearance marked the longtime band?s first time playing live alongside guitarists Mike Campbell, formerly of Tom Petty and the Heartbreakers, and Crowded House?s Neil Finn, both of whom stepped in after Fleetwood Mac fired Lindsey Buckingham in April. Both guitarists featured prominently in the performances, flanking to the left and right of Stevie Nicks; on both ?The Chain? and ?Gypsy,? Finn handled the vocal parts previously sung by Buckingham, particularly on ?The Chain,? where Finn and Nicks showcased their budding vocal chemistry.
