We aim, in this paper, to present a formal interacting string solution for the MigdalMakeenko Loop Wave Equation for the colour group (U(Nc)) (Ref. [1] and references therein). Our main tool to solve the Migdal-Makeenko Loop Wave Equation is based on the remark made in the Section 1 of this note, where we address the problem of solving critical string wave equations by string functional integral by applying simple rules of the operatorial calculus of Quantum Mechanics. We thus apply the results of Section 1 to present a string functional integral solution for the Migdal-Makeenko Loop Wave Equation for the colour group U(Nc).
