THE FULL lineup of concert and workshop talent for this year's Mariposa is available now, and it's perhaps the strongest ever, especially for the workshops.

In order, the events and personnel look like this:

Friday, Aug. 6, 9 p.m.: Concert with Gordie Lightfoot, Allen-Ward Trio, York County Boys, Elyse Weinberg, The Dirty Shames, John Hammond, Wade Hemsworth.

Saturday, Aug. 7, 11 a.m. to 12.30: Guitar workshop, with David Rae as host, and Charlie Waller, John Hammond, The Dirty Shames, Amos Garret, and Son House joining in.

Or, between 11.30 a.m. and 12.30 p.m., a children's concert with Sharon Trostin and The Travellers' Jerry Grey.

From 1 p.m. to 2.30 p.m., there's a banjo and mandolin workshop, with Eddy Adcock of The Country Gentlemen as host, and featuring David Rae and John Duffy.

After a 15-minute break, a blues workshop starts at 2.45 and runs to 4 p.m. Featured are John Hammond, Son House, Dick Flohill, John Norris and Amos Garret.

From 4 p.m. to 5 p.m., to make for a full Saturday afternoon, there'll be a composers' workshop, hosted by Ted Schafer, and featuring Ian Tyson, Phil Ochs, Gordie Lightfoot and Wade Hemsworth.

For the less scholarly, Saturday also offers the First Annual Mariposa Canoe Race at 3 p.m. for the Mariposa Trophy. At least the Festival producers hope so - what they need right now are contestants.

Saturday's concert is at 9 p.m., and features Ian and Sylvia, The Country Gentlemen, Phil Ochs, Joni Anderson, Son House, Bill Price and The Dirty Shames again.

Sunday, Aug. 8, has a ballad workshop between 12 noon and 1.30 p.m., Edith Fowke as hostess, with Sylvia Fricker Tyson, Bill Price, Owen McBride, Mrs. Clarke and Lotys Murrin.

The Sunday concert gets underway at 2 p.m., with Lotys and Russ, the Country Gentlemen and Gordie Lightfoot again, The Common Folk, Owen McBride and Sharon Trostin.

Following this, with the Festival's permission but not under its auspices, there will be a benefit concert for SNCC, featuring Phil Ochs and others not yet announced.

In case you've forgotten - the Festival this year is at Innis Lake; turn off the M-C Freeway on to the airport road, keep north until East Caledon and let the Festival posters direct you from there. It's about 25 miles from Toronto.

No camping facilities, but there are beaches, swimming, washrooms and a pavilion which holds about 1,200 in case of rain. There are parking facilities for 3,000 cars.
