Have you wished your brother or sister a happy Siblings Day today? Perhaps not if you’re in the United Kingdom, but in North America, the day honours the relationship of brothers and sisters of all ages and is recognised now in 49 states after governors started officially issuing proclamations to recognize Siblings Day since 1998.
Those of us fortunate to have a sibling will reveal that despite rivalries, spats and the usual trappings of having a younger or older sibling, most of the time there’s no one else they’d rather have for a brother or sister. But in the case of some of our musicians on this list, perhaps that statement doesn’t apply to everyone - we’re almost looking at you, Gallagher brothers.
So while you rush out to find a last-minute card to bestow on your beloved siblings, NationalWorld takes a look at some of our favourite, if not sometimes infamous, siblings in music.
