The second pair of rock's battling brothers (after the Everlys) were Ray and Dave Davies, who made lots of hits but didn't exactly leave enamored of each other. 

"Fisticuffs on stage were not uncommon, often involving drummer Mick Avory – the 'third Davies brother', according to Dave.

A concert in Cardiff came to an abrupt halt when Dave ended up in hospital after Avory hit him on the head with a cymbal.

Violence was never far from the surface. Ray was notorious for settling any and every argument with a well-aimed volley of punches."
