Erik Sandin joined NOFX in 1983. Two years later, in 1985, Scott Sellers replaced Erik. However, Scott joined a band called Meat Wagon and left NOFX.
Erik Sandin returned from Caustic Cause to drum with NOFX again, but quit the band again to go on vacation with parents to Idaho in 1986. Another drummer called Scott (this one with Aldahl as his last name) drummed for 2 weeks. The rest of the year till present it was Erik Sandin behind the drumkit. The third time seems definitive.
