Although Don Harrison was the lead singer and his name was lent to the band, the DHB was indeed a full band, rounded out by guitarist Russell DaShiell and, from Creedence Clearwater Revival, Stu Cook on bass and Doug "Cosmo" Clifford on drums.
These are videos from concerts where Don Harrison Band played, so they may be of other bands that played the concert as well.
