The songbook to four is now in record stores and some music stores
that carry sheet music. In the San Francisco area, I've seen it in Tower
and in Musicland/Sam Goody.
The inital copies are automatic shipments of new titles, Warner Bros sends
one of each new title to its retailers. If the store doesn't have it, you
can order it. The order number is PG9506. They may tell you that
it's not in the catalog - but this is a new title and the paper catalog
was printed a month ago. It sells for $24.95.
The last 32 pages contain complete transcriptions of every note of harmonica
on the album, both in written music and in tab (arrows and numbers under
the musical notes).
