The group was very successful, but its members had many different ideas, and could not always work well together. Tension grew between them, and they nearly disbanded. Young left to return to Crazy Horse, and tour with them on his own. Each of the four recorded a solo album during 1971, though, and each album became a hit. Nash and Crosby toured together, and Stills formed another band, called Manassas, with Chris Hillman of the Byrds. Another round of solo and duo albums was released during 1972, with Young's "Harvest" and its single "Heart Of Gold" becoming the biggest hits. Albums by the other members were not as successful, though they still sold well. Crosby and Nash got along very well, and worked together as a duo, while Stills joined Young and Crazy Horse to record Young's "War Song". Crosby also rejoined the Byrds, but the album they recorded together, "Byrds", was not a hit.
