He's the younger on my dad's side. The older on my dad's side is 29, and my half-brother on my mom's side is 30.
(my mom is 60 and my dad is 68 )
I think that the youngest (Ben) at least likes their 'hits' (Clocks, Viva, etc.). I haven't seen the older on my dad's side since I was seven, so I don't know about him, and I have no idea about my brother on my mom's side.
