Probably the only creatures who did not enjoy the Washington Revels' May Day celebration yesterday in the 3700 block of Brandywine Street NW were the Quailhill Farm sheep, who had the good sense to appear embarrassed while being shorn in front of hundreds of merrymakers. For everyone else it was an afternoon of fiddlers fiddling, Highlanders flinging and lots of singing.

Henry Chapin, one of the directors of "Bringing In the May," was an excellent May Fool; he kept the festivities moving brightly along by frequently employing the age-old theatrical gesture of the hand across the neck to signal the talented Greenwood Band to cut to the end of one group's music to get the next one on. The Washington Revels know how to throw a party, and there was never a dull moment. The May Revels Singers & Garland dancers provided some lovely singing throughout, but they were especially successful with the medieval "Sumer Is Icumen In." And the Foggy Bottom Morris Men, in a joint production with 14 sixth-grade boys from the Potomac School in McLean, were quite adept. Their rendition of a piece called "Rabbits in Australia" was delightful. The ladies of the Shepherdstown, W.Va., Northwest Clog Morris Team were energetic and polished. But the highlight of the program was the sylphlike Highland dancer Laura Scott, a spectacularly nimble and graceful performer. She was a joy to watch.
