Rod again topped the Billboard Singles charts for eight solid weeks and the Australian singles charts with the beautiful and romantic ballad, 'Tonight's the Night" accompanied with the music video (with featured Britt Ekland). 'Tonight's the Night' from the A Night on the Town album, which went to #2 on the Billboard album charts and was Rod's first platinum. Rod continued his 'fast side' 'slow side' trend which first showed up in 'Atlantic Crossing'. Cat Stevens' cover song, 'The First Cut Is The Deepest', went to the top 30 in the US in 1977 and made number 1 in the UK, (even thought it is widely rumored that the Sex Pistols' 'God Save The Queen', sold more records in that week). "The Killing of Georgie (Part 1 and 2)", is said to be about the murder of a gay man, was also a top 40 hit for Rod during 1977.
In 1978, Rod's continued success was proven when 'Foot Loose & Fancy Free' was a chart success, reaching number 2 positon and having the same characteristic sound as that from 'A Night on the Town'. "You're In My Heart" became a hit single and reached number 4in the US. reaching #4 in the US. The faster "Hot Legs" recieved much radio attention along with, 'I Was Only Joking'. By this time Rod's apparel and appearance was taking on a change (somewhat shocking to some) which included make-up, right fitting, silky spandex and other characteristics of the 'typical rocker. Perhaps he was preparing his public for the release of yet another hit, 'Da Ya Think I'm Sexy', which made number 1 in the US and was a crossover hit climbing to number 5 on the Billboard's black charts, due to it's slightly disco, soul sound. 'Da Ya Think I'm Sexy', was the lead single for the album 'Blondes Have More Fun', which rocketed to number 1 on the Billboard album charts and sold over 3 million albums. Sadly, this was to be Rod's last number one album for a quarter of a century.
