In addition to the recording artists in Band Aid,a number of performing artists and rock clubs are donating proceeds from their performances to Oxfam America's famine relief program.
For example, the cast of ''Forbidden Broadway,'' a satirical spoof of musicals, playing at the Boston Park Plaza Hotel and Towers, is donating proceeds from a benefit brunch on Sunday. The hotel is getting in on the act by supplying food and beverages for the brunch. The New York cast of the show is planning a similar venture.
Soul singer James Brown donated proceeds from his three concerts at the Lone Star Cafe in New York City last week.
Moli Steinert, Oxfam's special-events coordinator, says that several prominent singers are planning concerts to raise money for famine relief. Folk singer Tom Rush will donate proceeds from his special concert for children in Boston. Pete Seeger and Dick Gregory are planning a benefit in New York State in March.
''I've also gotten a number of calls from producers in San Francisco, Boston, New York, and Philadelphia, who have offered to help put concerts together,'' says Miss Steinert.
Arts groups aren't alone in their generosity and ingenuity:
*Yankee Lumber, in Canton, Mass., is donating double the proceeds of its entire Christmas tree season to Oxfam. After seeing a telethon about Ethiopia, president Henry J. Kruger said he wanted to ''get the company involved.'' If this year's sales equal last year's, the comapny's total donation will be $7,000 .
*Some New Hampshire and Connecticut florists have raised thousands of dollars by donating the proceeds from the sale of their flowers. Children pitch in by selling the flowers in the community.
*Andy Rose, a 10th-grader at Riverdale Country School in Riverdale, N.Y., has organized some 50 children from several schools. They have raised more than $13, 000 for Oxfam by going door to door in apartment buildings since Thanksgiving.
