Jan Akkerman is a bad-ass, and highly under-appreciated here in the USA. Van Leer is also a very talented musician, as well.
I always found it interesting that the original guitarist of the Vandals was Jan Nils Ackerman (though I have seen his name spelled differently, and this seems to be an Americanized version of a Dutch surname). Pretty sure they were are not related, as the younger Jan is from Southern California, USA. (edited)
