Yes. Like today, I was singing along to Blondie’s The Tide is High.
Yup. I’m a high tenor so I can carry up through most of the standard female ranges and even snip a note or two from the sopranos.
Remember The Music Man? I played the tenor (high voice) in the barbershop quartet.
I’m a big man, 350 lbs, 6’3". I’m the biggest guy on stage and I hit the highest note. It was good for a laugh every performance.
Yes, and I don’t change my pitch.
Absolutely; in fact, I think I do a pretty good “Lonely Nights” by Captain and Tennille and “As Tears Go By” by Marianne Faithfull, with no pitch change.
You should have seen my wife’s face the first time she heard me sing along with Cher! Unlike you, I was well aware of the association with the OLG–I just didn’t care!

Man, I would SO love to get you on a stage with my friend David. He’s 5’2" tall and maybe 130 pounds soaking wet, and he has the best basso profundo I’ve ever heard.

I had the same reaction. And from reading the replies, 99% of the SDMB population is of the “of course” frame of mind.
Tabby_Cat, if you’re still here would you elaborate on the thoughts that prompted your question?
When I sing along with a song, there’s an emotional outlet component and a role-playing component. I’m vaguely aware of the muffled frisson that arises from gender identity transference when I’m connecting with a chanteuse. I suppose the OP is curious if that sensation is uncomfortable for some people.
Among voluntary respondents, apparenty not many. But if a random sample of the population was tied down and brainscans were performed, would we find a significant representation of homophonophobes?
Maybe if they made everyone listen to musical porn… 
Ok, that was a stretch, but there’s a joke about that study in there somewhere!
Do I sing along? Yep. I’m currently, umm, making stuff up, to go along with some nice flamenco guitar. At least this way I can’t get the words wrong.
