hi joel

depends on your reason for wanting them combined

in the first query, you're keying on a particular weblog record, then
finding all loggenretlks linked to it, and all genres linked to those

in the second query, you're keying on the same weblog record, but then
finding all logbandtlks linked to it, and all bands linked to those

a more complex join would probably not make sense, unless the loggenretlks
and logbandtlks are also related to each other

you could combine the queries in a UNION, but then you'd have to
distinguish between the genres and bands, which would all come back in the
same column -- probably not what you want

if making one call to the database instead of two is your reason for
asking, leave them as two
