Apparently when Nick toured he insisted on using just the one acoustic guitar and as his songs varied from one tuning to another this involved quite a bit of time retuning between certain songs. This in turn led to quite a bit of frustration in the audience and he used to get quite a bit of heckling at times which upset him as he was quite a sensitive soul. Strange, whenever I saw Neil Young live his acoustic set compromised of half a dozen different guitars on stands in a half circle shape around him, plus a banjo and a piano and pump organ either side of the stage, never missed a beat Neil and he had plenty of banter and stories to tell too which were always well received by the audience. It is an entertainment business after all.
