Commercially the most successful Wigwam album must be the more pop-oriented Nuclear Nightclub that followed in 1975, with new members Pekka Rechardt on guitar and Måns Groundstroem on bass.
The band from Nuclear Nightclub on had songwriters Pembroke and Rechardt often working together, and the two came to describe the style as "deep pop" instead of progressive rock.
For a time in the 1970s Wigwam seemed poised to break through in Europe, along with bands like Tasavallan Presidentti, but even though they were highly praised by the UK press large-scale international fame eluded them, and by 1978 they had disbanded.
The latest line-up consists Mikko Rintanen, Jan Noponen, Måns Groundstroem and Jukka Gustavson with Pekka Nylund playing guitar.
In late 2018, the band made a short 50th anniversary tour in Finland with line-up of Jukka Gustavson, Jim Pembroke, Pekka Rechardt, Esa Kotilainen and Jan Noponen with Pave Maijanen on bass.
