While searching the web for video recordings of Jacob do Bandolim, I found out from his official website that just a sequence of appromimately 30 sec seems to exist, strange considering the popularity of this great artist.
Click picture to download the zip.file of the short tv spot showing an interviewer talking with Jacob, sound track has music by Jacob. Go to the index 'veja Jacob' to reach the download file.
More sound by Jacob do Bandolim available at his web
