We study interpolatory quadrature formulae, relative to the Legendre weight function on [-1, 1], having as nodes the zeros of any one of the four Chebyshev polynomials of degree n plus one of the points 1 or -1. In particular, we derive explicit formulae for the weights and examine their positivity,
