The Mello Souls was sdiscussed elsewhere and here some info from David Flynn that came about from the discussion...
The Mello Souls were from Wilmington, Delaware near Philly. The leader of the group was a guy called Silas Phifer, who had an earlier release as, 'Silas Phifer & the Mello Souls' on the James Chavis owned Candi/Chavis set up. Candi, Chavis & Mello are all from the same town and conversations Andy Rix had with various people associated with the Matadors and the Empires indicated that many of the members of these three groups were related and/or friends, and indeed moved from one group to another as required. The record was pressed at Virtue, and 'We can make it' was published by 'Mary Hill' Music, with the 'Mary' probably being Frank Virtue's wife.
Members of the Phifer family still live in the area, but have no 45s, and Silas currently resides in a care home. James Chavis still lives in Wilmington on Vandever Street...the same name he used for his publishing company, but he has nothing left either.
