I have the album.

This was the first of three "official" albums that Dave did for EMI with local folk performer Lionel Long.

The Bold Bushrangers was a double LP of 24 songs on which Dave played banjo on four tracks, but he did not sing.

He may have played some guitar on other tracks but I have not found any mention of that anywhere and I think it was unlikely.

On the two subsequent albums for EMI, Dave sang some background vocals on each album as well as playing banjo and possibly his 12-string Gibson.
