Fleetwood Mac are about to finish a run of London gigs at Wembley Arena -- and have admitted playing some of the hits from the band's tumultuous past can still be uncomfortable.

Singer Stevie Nicks told BBC 6 Music: "Somebody's playing a song, and everybody in the room is going, 'that's about me right?' And of course it's about you, but what you have to do is let that go, 'cos if you don't let that go, you can never play these songs for anybody."

The current tour includes the band playing all the hits from the mid-70s (pictured, minus drummer Mick Fleetwood), and has been hailed as a successful return after a relatively low profile this decade. The band famously suffered a serious of acrimonious relationships, with John McVie and wife Christine divorcing, and Nicks and guitarist Lindsey Buckingham also splitting.

Buckingham says reforming -- the mid-70s line-up reunited in 1997 -- was not easy. "It was kind of an exercise in denial that really was the only way to get through it, you really had to put your feelings over here and get on with what needed to be done in the rest of the room."

Fleetwood Mac formed in London in 1967, with the only founding member still in the band being Fleetwood. The current tour, which features all of the 'Rumours'-era band apart from Christine McVie, kicked off in North America in March.

"We'd just come back from New York, and I don't think the band has played better. This is a great body of work we've got and that allows you to sort of, all the other good feelings, and the other more objective and positive aspects of how you feel about the people, to follow," Buckingham said.

The London dates finish on Friday, and the band then tour Australia and New Zealand in December.
