Another copyright infringement case involving a hit song, this one from decades ago.

FOX's Lisa Lacerra reports:

Does this song...

Sound like this song?...

A federal judge ruling that lawyers for the late guitarist of the band Spirit have shown enough evidence to support a case that the Led Zeppelin song 'Stairway to Heaven' copies from the Spirit song 'Taurus'.

'Taurus' was written by Spirit guitarist Randy Wolfe in either 1966 or 1967. Led Zeppelin released 'Stairway to Heaven' in 1971.

Both bands performed at some concerts and festivals around the same time, but not on the same stage. The judge writing that the evidence presented so far represented a circumstantial case that Led Zeppelin may have heard 'Taurus' before 'Stairway to Heaven' was created.

The trial set for May 10 in Los Angeles. Led Zeppelin guitarist Jimmy Page and singer Robert Plant both named as defendants.
