6. Fleetwood Mac
For the first time in sixteen years, Fleetwood Mac reunited this year (2015) with their original lineup for the 'On With the Show' tour. Fans were besides themselves with anticipation for original Rumours lineup Mick Fleetwood, Stevie Nicks, Christine McVie, Lindsey Buckingham and John McVie. And the band didn't disappoint in their London 02 shows, with The Telegraph writing: 'there is really no way this band could be anything less than extraordinary.'
