The Pet Shop Boys sold more than 50 million records worldwide.

They became the most successful duo in UK music history.

They won numerous international awards, travelled the world on various concert tours, produced and wrote music for other major international musicians.

And they re-invented themselves several times over, much to the surprise of many in the music industry.

One of their singles, Always On My Mind, they re-imagined by giving it a techno-pop twist.

The song – the eternal theme of love, love lost, and regrets – became an international hit.

Other major musical stars such as Elvis Presley, Willie Nelson, also had recorded but the Pet Shop Boys took into a new musical dimension.
