Echoing "Low"s minimalist, instrumental approach, the second of the trilogy, ""Heroes"" (1977), incorporated pop and rock to a greater extent, seeing Bowie joined by guitarist Robert Fripp. Like "Low", ""Heroes"" evinced the zeitgeist of the Cold War, symbolised by the divided city of Berlin. Incorporating ambient sounds from a variety of sources including white noise generators, synthesisers and koto, the album was another hit, reaching No. 3 in the UK. Its title-track, though only reaching No. 24 in the UK singles chart, gained lasting popularity, and within months had been released in both German and French. Towards the end of the year, Bowie performed the song for Marc Bolan's television show "Marc", and again two days later for Bing Crosby's final CBS television Christmas special, when he joined Crosby in "Peace on Earth/Little Drummer Boy", a version of "The Little Drummer Boy" with a new, contrapuntal verse. Five years later, the duet proved a worldwide seasonal hit, charting in the UK at No. 3 on Christmas Day, 1982.
