Query: Once again about the reaction phi(1020)-> gamma-pi-pi   Gauge invariance constraints and analytical properties of the amplitudes e+
e- -> gamma-pi-pi and phi(1020) -> gamma-pi-pi are discussed in line with the
criticism of N.N. Achasov in hep-ph/0606003. I show that the formulae of our
paper (Yad. Fiz. {\bf 68} 1614 (2005) [PAN {\bf 68} 1554 (2005)],
hep-ph/0403123) have nothing common with those N.N. Achasov claims to be ours -
his criticism is therefore misplaced.
