misfits are has-beens gone cheeze metal (hence every trailer park metal kid with a misfits wallet) and ramones arent even around, nor is Joey around anymore, but yes, there is always a exception to the rule, but then Ramones are long since history, and only one member of the band was a sellout like that.
There is always an exception to the rule, heck the biggest skin band (skrewdriver) started punk then Ian Stuart turned sharply right overnight straight to nazi racist oi.
(sucks there music is still good even after they changed, their lyrics any neocon in here would love especially.)
I wouldn't call Ramones a very good example of punk and what it stands for, they had the energy and drive but they were basiclly pop ahead of their time in the sound.
(some would say a NYC style iggy pop/stooges ripoff, the ramones were pretty overated and not very punk)
