These guys aren't even close to being the band with the most volatile line up. The champ is the British blues and rock crew Savoy Brown who have been at it since 1965 and rotating out musicians along the way. Wikipedia lists over 40 members and this is probably not complete and only includes the "names." Estimates are closer to 80. Might not be fair since with one original member they are less band mates and more as sidemen, but with they are credited as members of the band.
