A few people got a look at Fleetwood Mac's new lineup when Mike Campbell joined Neil Finn on May 3rd.
The two legendary guitarists are replacing Lindsey Buckingham for Fleetwood Mac's upcoming world tour.
The joint performance took place at Finn's show with his son Liam in Los Angeles.
They played 'Man of the World' from 1969 when Peter Green was fronting Fleetwood Mac, and David Bowie's 'Moonage Daydream.'
According to Variety, 'Man of the World' was unrecognised by the crowd but 'Moonage Daydream' concluded with the the two trading guitar licks.
Later, someone shouted a request for 'Go Your Own Way' andFinn responded saying, "I should be ready to start it up by now. Just you wait.”
Fleetwood Mac will begin first part of their tour at the BOK Center in Tulsa on October 3.
