In 1976, he embarked on a short-lived but high-profile pop career, with three Top 20 hits in the UK Singles Chart "Reggae Like It Used To Be", "Dancing with the Captain", and "Grandma's Party", the last two of which reached the Top 10. He released the single "Heaven On The 7th Floor" in 1977. This only just reached the UK Top 40, but reached number No. 1 in New Zealand. In the US, the song peaked at No. 6 on the "Billboard" Hot 100 and number 5 in Cashbox listings, giving Nicholas a gold record. He followed this with "On The Strip" which entered the Billboard Hot 100 No. 67 but failed to enter the UK chart. In the mid-1970s he hosted his own children's television pop show, "Paul".
