    We give formulae for computing Kronecker coefficients occurring in the expansion of sΞΌβˆ—sΞ½s_{\mu}*s_{\nu}, where both ΞΌ\mu and Ξ½\nu are nearly rectangular, and have smallest parts equal to either 1 or 2. In particular, we study s(n,nβˆ’1,1)βˆ—s(n,n)s_{(n,n-1,1)}*s_{(n,n)}, s(nβˆ’1,nβˆ’1,1)βˆ—s(n,nβˆ’1)s_{(n-1,n-1,1)}*s_{(n,n-1)}, s(nβˆ’1,nβˆ’1,2)βˆ—s(n,n)s_{(n-1,n-1,2)}*s_{(n,n)}, s(nβˆ’1,nβˆ’1,1,1)βˆ—s(n,n)s_{(n-1,n-1,1,1)}*s_{(n,n)} and s(n,n,1)βˆ—s(n,n,1)s_{(n,n,1)}*s_{(n,n,1)}. Our approach relies on the interplay between manipulation of symmetric functions and the representation theory of the symmetric group, mainly employing the Pieri rule and a useful identity of Littlewood. As a consequence of these formulae, we also derive an expression enumerating certain standard Young tableaux of bounded height, in terms of the Motzkin and Catalan numbers
