Anyone interested in either of these singers who has access to Google has probably already worked out the "yeah, yeah" sample from Cheers is from Lavigne's 2002 song I'm With You, released when she was 18.
That was her "mature" song, the third single from her first album after her breakthrough alt-pop hit Complicated and Sk8er Boi.
In complete contrast to Cheers and its party hard theme, I'm With You is powerfully depressing. Even the "yeah, yeah"s (the same ones that sound ecstatic for Rihanna) sound sad. One critic said it was "the perfect song to drown your sorrows to when that guy from your class breaks your heart". The same critic said it was the sort of song you'd expect to turn up on Dawson's Creek (Both observations give a good clue as to Lavigne's target audience but the link between schoolkids and drinking may be a bit off).
The former teen star is 27 next month, but funnily enough none of her current crop of tunes seems as mature as this early track.
It's an inspired choice for Team Rihanna to sample.
I'll drink to that.
Yeah Nah - putting the cult in pop culture since 2011
