4. The judge allowed fees for plaintiffs’ attorneys under G. L. c. 93A, § 9(4), in the amount of $9,695. The question is raised whether, at any stages of the case where two attorneys appeared for the plaintiffs and compensation for both was claimed and allowed, one attorney could reasonably have done the job. See Hager v. Hager, 12 Mass. App. Ct. 887, 889 (1981); Grendel's Den, Inc. v. Larkin, Nos. 84-1313, 84-1314, slip op. at 8, 15-16 (1st Cir. Dec. 5, 1984). The judge, with intimate knowledge of the matter, may well have considered and implicitly answered the question in making the allowance, but he did not advert to it expressly in his findings. We cannot respond to the question independently. Out of abundant caution, we hold that the judge on remand should deal with the question, with liberty *961in his discretion to receive further evidence. At the same time the judge should fix reasonable fees in favor of the plaintiffs for the work of their counsel on this appeal.
