This is a fine example of a top quality, new wave soul tune, and it's a timeless classic that almost everyone remembers from the 1980s although I was not heavily into soul music at the time. I was a young teenager who had been brought up on rock music, and in the 70s I listened to a lot of Suzi Quatro and my Mum's rock n' roll records from the 1950s and 60s. I was also a fan of trashy disco music, with Ottawan's D.I.S.C.O. being a firm favourite - if only I had paid more attention to soul music!

Inside Out was the final hit to break in the UK Top 40 for Odyssey, reaching #3 on 27th June 1982, where it stayed for two weeks before falling to #4 on 11th July. The track was released as the lead single from the band's fifth studio album Happy Together. This was the group's highest charting album in the UK, reaching #21 during 1982. Overall, the band's albums were not massively successful and this was the final album to chart anywhere for the group. 

Inside Out was also a #2 hit in Ireland and reached #22 in the Dutch charts. The single also peaked at #12 on the U.S. R&B chart. Interestingly, the chart was renamed "Hot Black Singles" around the same time (it was previously called the Hot Soul Singles chart), and this name was used until 1990.
The follow-up single to Inside Out was Magic Touch, although this was nowhere near as successful, stalling just outside the British Top 40 at #41.
Overall, the U.S. band achieved success with five top ten hits in the UK between 1977 and 1982.
After listening to Inside Out on Youtube for the first time in many years, I can now appreciate the musicianship that went into the track. I now wish that I had listened to more of this stuff when I was younger, although it is only when you reach a certain age that you suddenly realise you were listening to too many throwaway pop songs when you were a teenager!
