The breakthrough for the band in the US came when they had a No. 1 pop charts hit in early 1977 with Bruce Springsteen's "Blinded by the Light". While the Springsteen original from 1973's Greetings from Asbury Park, N.J. album has a folky, acoustic sound, the Manfred Mann's Earth Band version is driving rock, combining Mann's Moog synthesizer and organ work with Flett's guitar. Manfred can be heard singing at the end of "Blinded by the Light", in the round, with Thompson - it was this feature of the song that initially attracted him. The band took advantage of the publicity and re-released another Springsteen song, "Spirit in the Night", which had been recorded the previous year on Nightingales and Bombers, originally with Rogers on vocals although for some territories it was re-recorded with a vocal from Thompson.
