McShane learns at a young age to play bass and guitar. As a teenager, he is allegedly shunned by his family after they learn of his homosexuality. Later as a young man in the late 1970s, he leaves Northern Ireland to study at a stage school in London, where he learns to dance, sing and recite.
Hired as a stage dancer and backing singer, McShane soon goes around Europe with Dee D. Jackson and her band. During a visit to Italy with the band, he is attracted to the country’s underground dance scene, which leads to him settling in Milan in 1984. He tells Dick Clark on American Bandstand in 1986 that he fell in love with Italy from that moment. He also learns the Italian language.
McShane makes his debut playing in small clubs in his hometown and is presented to various audiences, without success. In view of his low artistic success, he decides to work as an Emergency Medical Technician (EMT) for the Red Cross until he meets Italian record producer and keyboardist Maurizio Bassi, with whom he creates Baltimora. The act finds success with its most popular single, “Tarzan Boy”, released in 1985.
In the United States, McShane is overwhelmed with the success of “Tarzan Boy”. Some sources state lead vocals are performed by Maurizio Bassi, the group’s keyboardist, with McShane actually providing the backing vocals. This still remains uncertain, and McShane lip synchs while appearing in the “Tarzan Boy” music video, and not Bassi. Both the music and the lyrics of Baltimora are written mostly by Bassi and Naimy Hackett, though McShane writes the lyrics to some of their songs, such as the single “Survivor in Love.”
After the release of “Survivor in Love,” with no label support for a follow-up album and due to its poor success, Bassi decides it is time to move on to other projects and Baltimora disbands.
The single “Tarzan Boy” bounces back into the Billboard Hot 100 chart in March 1993 as a remix, climbing to No. 51, at the time of its appearance in a Listerine commercial. The song is also featured in the films Teenage Mutant Ninja Turtles III (1993), Beverly Hills Ninja (1997) and is then referenced in A Million Ways to Die in the West (2014).
McShane is diagnosed with AIDS in Milan in 1994. A few months later he returns to Northern Ireland to spend his final year, and dies in his native Derry on March 29, 1995 at the age of 37. A family spokesman issues the following statement after his death: “He faced his illness with courage and died with great dignity.” In the centre of Derry, a commemorative plaque is bestowed upon the grave of McShane and his father, who had died three years prior.
