a brisk walk in the park.
a festive (or festal) occasion.
a jovial old gentleman.
a lively gait.
a merry chase.
a merry evening.
a mirthful laugh.
a poet could not but be gay, in such a jocund company.
a snappy pace.
a spanking breeze.
gay and exciting night life.
have a merry Christmas.
jolly old Saint Nick.
peals of merry laughter.
the jolly crowd at the reunion.
traveling at a rattling rate.
when hearts were young and gay.
