What was the original name of the song "Blinded by the light" produced later in 1977 by the British rock group Manfred Mann's Earth band?

"Spirit in the Night" is a song written and originally recorded by New Jersey-based singer/songwriter Bruce Springsteen for his debut album Greetings from Asbury Park, N.J. (1973). It was also the second single released from the album. A cover version titled Spirits in the Night (spirit being plural), performed by Manfred Mann's Earth Band, was released on the album Nightingales and Bombers and was a top 40 single.

The Manfred Mann's version differs from Springsteen's version mostly in its arrangement, relying heavily on keyboards and using different harmonies in the chorus. Manfred Mann's Earth Band again released the song as a single with the titles "Spirit in the Night" (U.S. and Australia) and "Spirits in the Night" (other parts of the world), this time with vocals by Chris Thompson. That version reached Billboard's Top 40, peaking at #40. This version was released as a bonus track on the 2004 CD release of The Roaring Silence. "Spirit in the Night" was to be the first of three songs from the Greetings from Asbury Park, N.J. album that Manfred Mann would cover — the others being their #1 hit "Blinded by the Light".
