I’m relatively new to this also, but here’s my take…
I looked at 2 transcriptions I found, listened to the chorus a few times, and tried what you had on my piano vs what the transactions had.
I think it’s better without a slur or glissando. The “hap-py, heal-thy” doesn’t seem to have any legato in the recording, not quite staccato, but the notes sound articulated separately in the B - E - B - E to me.
The transcriptions just have those 4 notes as 1/4 notes, and I feel that is correct.
