Can you sing harmony? Like classic rock?

We are a 3 piece classic rock group. We are all around 50, but age does not matter! A fun attitude does though! Male or Female or ? (just thought we'd throw the 'or' in there)) Looking for someone that knows how to and wants to sing HARMONY to our melody line! A good example of songs with 'harmony' would be to listen to the following: - Take it Easy, by the Eagles. Its the 'background voices' that are the harmony. (not the main singer) or - mama's and the papa's 'California dreaming'. (we don't do this song, but its a great example of harmony) or- -Simon and Garfunkel 'Cecelia'. you will hear that both voices are doing 'different' things here. (we don't do this one either....we're not that good lol) Most of our tunes are rock stuff you would hear on the Q radio station. Meaning, our tunes are a bit on the heaver side of things...All upbeat dance tunes, mostly. Of course we can do 'Brown Eyed Girl' and 'Take it easy' together but we like the rockier stuff too for sure........! We play the songs at a fairly high level (accurate to the studio recording in most cases), however, we would like to add harmonies into as many of the songs as possible, to 'fatten up' the vocals, EVEN IF THE ORIGINAL SONG DOESN'T HAVE HARMONIES........Heck, lets try to add your harmony to all of the songs! Come on! If you love music, don't worry about being embarrassed.......we are just regular folks...we make mistakes too...We are not professionals..... Time is short, take a chance......if it doesn't work, no big deal. This is completely just for fun! We'll rent a studio for 3 hours and see what happens! Getting down to business: THE 5 REQUIREMENTS: (some duplicates below) - Need to be able to sing harmony! - need to like 'rock' type music (not heavy metal, just rock) - have your own microphone - be reliable - cannot cancel 2 hours before a practice (due to some past experiences!) Please note that these rehearsal spaces cost money. Please don't say you can come and then change your mind 2 hours before....It really ruins it for all the people involved. Thanks for the consideration.
