I'm going to hope that it was in error that you sent this off-list, or
at least that you won't mind my replying on-list. Here's one way to do
it:

t = ['Start','End']
a = [[1,2,3,4],
     [5,6,7,8]]
result = []
for cur in a:
     result.append("%s - %d"%(t[0],cur[2]))
     result.append("%s - %d"%(t[1],cur[3]))
