Sharon Isbin has a CD entitled Road to the Sun/ Estrada do Sol. Apparently the transcription was made by Barbosa LIma but I don't if it was published. The CD was issued by Virgin.
The official site for Mr. Jobim has lots of music in simple arrangements for piano. You can find one for Estrada do Sol (for piano): http://www2.uol.com.br/tomjobim/musicas ... betica.htm
Or you can try to conotact the Instituto Antônio Carlos Jobim http://www.jobim.org/acervo/acervodigital.html
