4PK was a very short-lived Dutch garage/freakbeat band from the city of Eindhoven, The Netherlands, fronted by Peter Koelewijn, one of The Netherlands' earliest rock-'n-rollers (of Peter Koelewijn & Zijn Rockets fame). 4PK released four 7-inch singles in 1966 and may be seen as a temporary side-project of Koelewijn. Personnel: Peter Koelewijn: guitar, vocals Hans Sanders: guitar Karel Jansen: bass Jeroen Ophoff (or Frits van Antwerpen): drums <a href="https://www.last.fm/music/4PK">Read more on Last.fm</a>.
