SQL Joining two tables and relabeling them

I am using an SQL Database, which is a DBMS. Its the Lyric Database. (I'll be happy to clarify if my description is insufficient).

I need to list all the IDs of one table (the salesids) ONLY if they represent a studio AND ONLY if they have a contact named "Harry Lee".

My salespeople table (with the salesids) is as follows:

SalesPeople
-----------
SalesID, FirstName, LastName

and my Studios table is as follows:

Studios
-------
StudioID, Name, City, Contact, SalesID

I have started the Query in the following way:

select st.salesid, coalesce(sp.salesid, 'Does Not Work With Harry Lee') Does This Match Harry Lee?
from studios st
inner join salespeople sp on sp.salesid = st.salesid;

and as well:

select st.*
from studios st
inner join salespeople sp
on sp.salesid = st.salesid
where st.country = "Harry Lee";

But I am unsure as to relabel the column. I know to relable the column (as I sort of hint in the query above with the coalesce function).

However, how to I include that in the prior query whilst still adhering to the specifics of question? And again, I'll be happy to clarify the question if my description is insufficient.
