Much of my reaction is already noted by others, but there is also this--when an "instrumental" is created by someone who is attentive to and experienced in the lyrical aspect of writing, you can immediately detect this in the melody and song structure--it is very obviously sing-able, once someone decides to construct a sound lyric to it. Attention to accent points, the important repetitions in the phrasing--these are all underlayings that can support a great lyric and vocal, as is seen here. Contrast this with many "instrumentals" that are superb but cannot be made into songs that are "singable". Being familiar with Alan's work--both lyrics and literary works--I know that this awareness of "how the words might fit" is a key element of many of his non-lyric posts. Great work all the way around!!
