I sat down with Plessix 's and Grahame 's versions , read them side by side , both for the first time , and I can 't say that one is better , other than the significant fact that Grahame dreamed it all up in the first place ( although the fact that we wouldn 't have Mendelssohn 's " A Midsummer Night 's Dream " without Shakespeare 's does nothing to diminish Mendelssohn ) .
