Belle and Sebastian Get Mascara From Fans, Cover Pulp at Primavera Sound

"But when she's on her back/She had the knowledge/To get her into college," Stuart Murdoch -- and a good chunk of the crowd at Primavera Sound on Friday, May 27 -- sang during 'Stars of Track and Field.' Then the Belle and Sebastian frontman had a revelation.

"It just occurred to me that was not the last time you'll hear the rhyme 'knowledge' and 'college' tonight," he said, referring to the first two lines of 'Common People' and the fact that Pulp would take the San Miguel stage next.

Primavera Sound was also not the first time Murdoch had a fan apply mascara to him for 'Lord Anthony,' (because of the lyric "blue mascara running over your eye"), or brought a group of people up to dance to 'Legal Man' and 'The Boy With the Arab Strap' and then gave them "Olympic medals." But where better than a festival? With the video screen camera on her, the lucky front-row resident who darkened Murdoch's lashes was, understandably, quite worried about poking him in the eye.

A big band (made bigger on this night with trumpeter/bassist Mick Cooke replaced by two separate people) that has never lacked showmanship, Belle and Sebastian made for a commanding headliner, keeping the crowd happy with those antics and a mix of their most raucous ('I'm a Cuckoo,' 'The Blues Are Still Blue') and beloved ('Judy and the Dream of Horses,' 'If You're Feeling Sinister') songs.

And when Murdoch went into the crowd to gather dancers during the bridge of 'Legal Man,' impish singer-guitarist Stevie Jackson filled the empty vocal space with something truly unexpected, belting out three quick refrains of the Pulp song 'Common People': "Wanna live with common people like you/Wanna live with common people like you/Wanna live with common people like you." The crowd sang along to that as well, though not as loudly as they would during the next band's set.
