BLOOMINGTON, Ind. (AP) _ One of rocker John Mellencamp's sons has bonded out of a jail after he and his brother were charged with punching and kicking a man during a fight.
 
  A Monroe County jail officer says 18-year-old Speck Mellencamp was released on $500 cash bond shortly after noon Friday.
 
  Speck and his brother, 19-year-old Hud Mellencamp each are charged with one count of battery resulting in serious bodily injury.
 
  Nineteen-year-old Indiana University walk-on Ty A. Smith was also charged. 
 
  Documents allege Speck Mellencamp punched 19-year-old Alexander Bucy in the face on the porch of Bucy's Bloomington home on July 29 , believing that Bucy had hit him earlier that evening.
 
  The brothers and Smith allegedly “punched, kicked and stomped'' on Bucy, who suffered facial injuries.
 
  The singer's home is in southern Indiana.
